In order to make the monitor safe grounding, the hospital must provide the power socket with complete wire under voltage, zero line and protective grounding in accordance with national standard. Or the hospital bears all consequences. To ensure patient safty, verify the divice and accessories can function safely and normally before use. Only qualified accessories can be used for the monitor. The ECG cable uses five-lead or three-lead cable, and cannot be connected to other signal terminals. In order to avoid losing time for diagnosis and treatment, please configure adequate alarm settings according to different conditions of each patient (for detailed setting methods, refer to ALARM SETTINGS in CHAPTER 5). When using this monitor, the F-type application section cannot be connected to other conductivity or ground. When using the electrosurgery unit during the monitoring, the loop of the electrosurgery unit shall be properly connected to prevent from burning, even the life risk. The monitor must be operated on battery power if the external wiring is in doubt. When various equipments are connected to the same patient, pay attention to the danger of leakage current overlap. The Monitor has no defibrillation synchronization, so it cannot be connected to the synchronization defibrillation instrument. Magnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason make sure that all external devices operated in the vicinity of the monitor comply with the relevant EMC requirements. Mobile phone, X-ray equipment or MRI devices are a possible source of interference as they may emit higher levels of electromagnetic radiation. EXPLOSION HAZARD: Do not use this device in the presence of flammable anesthetics, explosive substances, vapors or liquids.

FUNCTION The G3 Multi-Parameter Patient Monitor can be used to monitor the major parameters such as electrocardiogram (ECG), body temperature (TEMP), impedance respiration (RESP), oxygen saturation (SpO2), invasive blood pressure (IBP), noninvasive blood pressure (NIBP) and CO2 (EtCO2 and FiCO2). It integrates the parameter measurement, display and record export as a whole, which forms a compact and portable monitor. The monitor is capable of monitoring the following parameters: ■ Electrocardiogram (ECG): heart rate (HR), 7 (or 3) leads ECG waveforms and ST segment analysis. ■ Noninvasive blood pressure (NIBP): systolic pressure (SYS), diastolic pressure (DIA) and mean arterial pressure (MAP). ■ Body temperature (TEMP): temperature of channel 1 (T1), temperature of channel 2 (T2) and temperature difference between the two channels (△T). ■ Pulse oxygen saturation (SpO2): SpO2, pulse rate (PR) and SpO2 plethysmogram. ■ Respiration: respiration rate (RR) and respiration (impedance respiration or nasal tube respiration) waveform. ■ Invasive blood pressure (IBP): 2 channels of IBP waveforms, systolic pressure (SYS), diastolic pressure (DIA) and mean pressure (MEAN). ■ Carbon dioxide (CO2): end-tidal carbon dioxide (EtCO2), fractional inspiratory carbon dioxide (FiCO2) and CO2 waveform.

The battery is charged automatically when the monitor is connected to AC power, no matter the monitor is powered on or not. The battery symbol displayed on the main screen tells the status of the battery. 31

( or The battery is installed in the battery slot.The ) grid part indicates its capacity. ■ (red and flashing) No battery is installed in the battery slot or the electrical volume is to be exhausted. Besides, the charge indicator also indicates the status of the battery. ■ ON The battery is being charged or the battery is fully charged. ■ OFF No battery is installed or the battery is installed but the monitor is not connected to AC power. The capacity of the battery is limited. When the battery capacity is too low, a flashing red symbol shows in the status bar. At this moment, the AC power shall be applied to the monitor. ■

NOTE ●

Take out the battery before the monitor is transported or will not be used for a long time.

WARNING ● ●

Keep the battery out of the reach of children. Only use the battery specified by the manufacturer.

BATTERY MAINTENANCE Conditioning a Battery A battery should be conditioned before it is used for the first time. A battery conditioning cycle is one uninterrupted discharge of the battery. Batteries should be conditioned regularly to maintain their useful life. Condition a battery once when it is used or stored for two months, or when its run time becomes noticeably shorter. To condition a battery, follow this procedure: 1. Disconnect the monitor from the patient and stop all monitoring or measuring. 2. Insert the battery in need of conditioning in the battery slot of the monitor. 3. Apply AC power to the monitor and allow the battery to charge uninterrupted for 10 hours. 4. Remove AC power and allow the monitor to run from the battery until it shuts off. 5. Apply AC power again to the monitor and allow the battery to charge uninterrupted for 10 hours. 6. This battery is now conditioned and the monitor can be returned to work.

Checking a Battery The performance of a rechargeable battery may deteriorate over time. To check the performance of a battery, follow this procedure: 1. Disconnect the monitor from the patient and stop all monitoring or measuring. 2. Apply AC power to the monitor and allow the battery to charge uninterrupted for 10 hours. 32

3.

Remove AC power and allow the monitor to run from the battery until it shuts off. 4. The operating time of battery reflects its performance directly. Please replace the battery or contact with the maintenance personnel if its operating time is significantly lower than the specified time.

NOTE ●

●

Life expectancy of a battery depends on how frequent and how long it is used. For a properly maintained and stored lead-acid or lithium ion battery, its life expectancy is about 2 or 3 years respectively. For more aggressive use models, life expectancy can be less. We recommend replacing lead acid batteries every 2 years and lithium ion batteries every 3 years. The battery might be damaged or malfunctioned if its operating time is too short after being fully charged. The operating time depends on the configuration and operation. For example, measuring NIBP more frequently will also shorten the operating time.

BATTERY RECYCLING When a battery has visual signs of damage, or no longer holds a charge, it should be replaced. Remove the old battery from the monitor and recycle it properly. To dispose of the batteries, follow local laws for proper disposal.

WARNING ●

Do not disassemble batteries, or dispose of them in fire, or cause them to short circuit. They may ignite, explode, leak or heat up, causing personal injury.

CHAPTER 5:

ALARMS The monitor gives audible or visual alarms to indicate the medical staff, when a vital sign of the patient appears abnormal, or mechanical or electrical problems occur to the monitor.

ALARM CATEGORIES The alarms are divided into two categories:

Physiological alarms A physiological alarm either indicates that a monitored physiological parameter is out of specified limit or indicates an abnormal patient condition.

Prompt information Besides the physiological alarm, the monitor also displays the information related to the system. For example, if a parameter module is turned on but the required leads or sensor are not connected, the monitor will prompt accordingly, such as “Lead Off” in the ECG and RESP channels, “Sensor Off” in the PLETH channel, or “No Cuff” under the NIBP parameter, etc. Prompt information is usually displayed in the channels area. But the prompt information relating to NIBP is displayed under 51

the NIBP value in the parameters area.

ALARM MODES When an alarm occurs, the monitor raises the user’s attention by the following audible or visual indications.

Visual alarms When a measured physiological parameter value exceeds the preset alarm limit, the alarm indicator on the front panel flashes in red once a second.

Audible alarms When a measured physiological parameter value exceeds the preset alarm limit, the monitor phonates a triple-beep tone each three seconds to prompt users.

Character flashes When a measured physiological parameter value exceeds the preset alarm limit, or a lead or sensor is disconnected to the monitor, this parameter value in parameters area or the prompt information in the corresponding channel flashes once a second.

CHAPTER 12:

ECG MONITORING OVERVIEW This Monitor adopts 5-lead (or 3-lead) ECG cable to collect the ECG signal from the patient, and it can simultaneously display seven (or three) leads of ECG signal. ECG channel displayed on the top part of the screen is the major channel of the ECG signal, and its lead is called the major lead. The Monitor calculates the heart rate value and controls the gain (if set in automatic mode) according to the data of the main lead. All leads adopt the same gain and same measurement mode. The Monitor can separately check whether the connection of a lead has fallen off, and display the promt information in corresponding channel.

1.Measurement of ECG The electro-chemical activity of “Excitable cell” will produce physiological current to cardiac muscle before the mechanical shrinkage of heart, the close movement current produced by the process of heart exciting will flow within the human body and transport to all parts, it results in the different voltage on the different surface of body. The clinic Electrocardiography is to record the voltage difference real time. Figure 2.1 is the Electrocardiography R P QS

2.1 Figure 1.1Electrode of ECG Current within human body is conducted by hydronium, while it’s by electron in metal conductor, so there should be a conversion medium to convert the hydronium current to electron current, which will help realize the necessary connection between the human body and patient monitor, electrode is to play the role to realize the transformation. The widely used electrode for clinic monitoring is Ag—Ag.Cl disposable electrode. 1.2. ECG leads The definition of lead is the periodically changing waveform with heart beating caused by the voltage between two or more than two surface parts of human body. One lead waveform can only reflect one aspect of the heart movement since the 74

heart is solid, so it’s necessary to record several leads waveforms to reflect the complete movement of heart from different respects during the process of diagnosing. Below table is the definition for the different leads of ECG: Table 2.1: Definition for different leads of ECG Name of leads Definition of leads Nominate of leads Ⅰ Ⅰ=LA-RA Standard double poles limb lead Ⅱ Ⅱ=LL-RA Standard double poles limb lead Ⅲ Ⅲ=LL-LA Standard double poles limb lead aVR=RA-(LA+LL)/2 aVR Pressure single pole limb lead aVL aVF Ⅴ

Our patient monitor adopts five leads ECG cable to collect signal of patient’s ECG. It displays synchronously seven ECG waveforms. The fixed channel of ECG displayed on the upper position is the main one of ECG signal, we call the ECG lead which the main channel choose “main lead”, patient monitor calculate the value of heart rate and control the gain based on it (if them monitor is set to model of “Auto gain”). We have the same gain control and test mode to all leads, the patient monitor is able to check whether the corresponding electrode of leads is fall off and display it on screen.

2.Monitoring of ECG electrode It can get mostly twelve selectable ECG leads if use five leads ECG cable to monitor patient’s ECG, the ECG waveform of this lead of patient will be displayed when the leads is set as valid. The ECG cable includes two parts: main stem cable which connected to patient monitor and Lead cable electrode which connected to patients, usually the ECG cable has five electrodes, please note below items when place the electrodes to patients: 1） How to choose and use electrodes It usually chooses Ag-AgCL one-off electrode, please make sure the electrodes are during the period of validity. It will result in inaccurate data if use the incompetent electrodes. 2） Pretreatment of skin It’s necessary to pre-treat the skin of patient to ensure the good touch between electrode and patient since the skin is not a good conductor. (1) Clean the skin with soap and water instead of aether and alcohol since the later two will increase the resistance of skin. (2) Shave off the fur of body where to place the electrode if necessary. (3) Rub skin to increase the blood floor of capillary vessel of organization and get ride of the horn and grease. 75

(4) Place the electrode to patient, please apply conductive cream before the electrode is put to patient if the electrode do not have conductive cream. (5) Connect the electrode and ECG cable. (6) Make sure the connection of patient monitor power.

ECG MONITORING In order to monitor the patient’s ECG, we use a five-electrode ECG cable by which we can get more than 12 selective ECG leads. If a lead is effective, the corresponding waveform will be displayed in the channels area. The ECG cable includes two parts: the main cable connecting the Monitor and the electrode lead line connecting the patient.

Select electrode Generally, the electrode for monitoring is disposable electrode made from Ag-AgCl (silver silver chloride). But before use, you shall confirm that the electrode is within the valid date. If the unqualified electrode is used, it will lead to inaccurate monitoring result. Skin pretreatment Because the skin is not a good conductor, if you want to gain good contact between the skin and the electrode, before installing the electrode, you shall carry out skin pretreatment at first. (1) If necessary, shave hair from skin at choosen site. (2) Rub the skin to accelerate the blood flow in the blood capillary of organs and remove the horny layer and greases of the skin. (3) Thoroughly cleanse the site with mild soap and water solution, but do not use the aether or pure alcohol, because it will increase skin resistance. (4) Dry the skin completely before applying the electrodes. Attach the ECG lead to the electrodes prior to placement. Place the electrode on the patient. If the conductive ointment is not applied to the electrodes, apply it before the placement. Connect the electrode lead to the patient cable. Confirm the Monitor is powered on and is ready for monitoring.

ELECTRODE PLACEMENT (1)

For the placement of the five–lead ECG electrode, refer to the figure as shown in Figure 12-1.

White (right arm or RA) electrode: near the right shoulder, directly below the clavicle. ■ Black (left arm or LA) electrode: near the left shoulder, directly below the clavicle. ■ Green (right leg or RL) electrode: on the right abdomen. ■ Red (left leg or LL) electrode: on the left abdomen. ■ Brown (chest or V) electrode: on the chest. ■

(2)

When using five leads, attach the chest (V) electrode to one of the following positions indicated in Figure 12-2:

Figure 12-2 Positions of Chest Electrode In order to accurately install and monitor the "V" lead, it is very important to determine the fourth rib position, which is determined according to the first rib position. Because of the patients’ different bodily forms, it is difficult to accurately feel out the first rib position. At first, feel out the small protruding body called the "Lewis angle", where the breastbone diaphysis and manubrium sterni joint. Then determine the second rib position, the protuberant section of the breastbone indicates the joint of the second rib, right under here is the position of the second rib position, from the chest to feel down until the fourth rib position is determined. Attach the chest (V) electrode to one of the following positions indicated in Figure 12-2: 77

V1: On the 4th intercostal space at the right sterna margin. ■ V2: On the 4th intercostal space at the left sterna margin. ■ V3: Midway between V2 and V4 electrodes. ■ V4: On the 5th intercostal space at the left clavicular line. ■ V5: On the left anterior axillary line, horizontal with V4 electrode. ■ V6: On the left middle axillary line, horizontal with V4 electrode. ■ V3R-V7R: On the right side of the chest in positions corresponding to those on the left. ■ VE: Over the xiphoid. When attaching the chest electrode to the back of a patient, place it at one of the following sites: ■ V7: On the 5th intercostal space at the left posterior axillary line of the back. ■ V7R: On the 5th intercostal space at the right posterior axillary line of the back. ■

Electrode placement for surgical patient Electrode placement during surgery is dependent on the type of surgery being performed. For example, with open chest surgery, the electrodes might be placed laterally on the chest or on the back. In the operating room, artifact can sometimes affect the ECG waveform due to the use of electrosurgery equipment. To help reduce this, place the electrodes on the right and left shoulders, the right and left sides near the stomach, and place the chest lead on the left side at mid-chest. Avoid placing the electrodes on the upper arms. This will cause the ECG waveform to be too small.

NOTE ●

Select the place with stable ECG signal or little inference of skeleton activities to place the 78

electrodes.

WARNING ● ●

●

●

●

●

●

In order to ensure the patient’s safety, all leads shall be connected to the patient. The electrode shall be fixed properly to ensure the reliable contact of the conductor with skin. Interference from a non-grounded instrument near the patient and ESU interference can cause inaccuracy of the ECG waveform. When using Electrosurgery equipment, never place the ECG electrodes near the grounding plate of the Electrosurgery device. This will cause a great deal of interference with the ECG signal. The patient leads should be placed in a position that is equal distance from the Electrosurgery electrotome and the grounding plate to avoid burns to the patient. Always dispose of, or recycle electrodes properly to prevent from environment contamination. Verify the lead fault detection prior to the start of monitoring. Unplug the ECG cable from the ECG connector, the flashing error message “Lead Off” will be displayed in the corresponding ECG channel. Skin irritation may result from the continuous application of the ECG electrodes. These should be checked each day. If there is an indication of excess skin irritation, replace the electrodes or change the location of the electrodes every 24 hours.

Select this button, the main lead switches among I, II, III, aVR, aVL, aVF and V. In order to get accurate heart rate and gain control performance, the doctor shall select the lead of large range and little noise as the main lead. In order to avoid emerging leads repeatedly, when the lead in the current channel is switched, the leads in the other channels will be changed automatically. Gain Mode Select this button, the gain mode switches between AUTO and MANUAL modes. Gain means the magnification times for the ECG waveform signal. This monitor has five magnification times that are ×1/4, ×1/2, ×1, ×2 and ×4. The ×1 is one time magnification, under which the range ⑦ of the scale ⑧ at the left side of the ECG waveform is 1mV. Then under the condition of ×2 magnification, the range ⑦ of the scale ⑧ is 0.5mV, and so on. Detailed data refers to the following table: Gain factor

Under 1 ECG and Huge Digit display format, the length of the scale ⑧ is 10mm. The waveform of 10mm diaplayed under ×1 magnification times means the ECG signal is 1mV, under ×2 means 0.5mV.

NOTE ●

All leads including the main lead and other leads adopt the same gain. This Monitor provides two methods to regulate the ECG waveform range: ● AUTO mode: Under the AUTO mode, according to the main lead waveform data, the Monitor will automatically regulate the gain to amplify the ECG waveform of the main lead without the distortion as possible. The defect of this mode is slow regulation speed. ● MANUAL mode: Under this mode, the Monitor doesn’t regulate the ECG gain automatically. At this time, the ECG gain is regulated via the Adjust Gain button. The feature of this mode is fast response that the waveform will change immediately after the gain is regulated, and the waveform can be amplified to a distortion status to display.

■

Adjust Gain Manually regulates the ECG gain. After selecting this button, regulate the gain via the rotating mouse. Rotate counterclockwise, the gain and waveform range become smaller, while rotate clockwise, the gain and waveform range become larger. After the accomplishment of the regulation, press down the rotating mouse again to exit the gain adjusting mode.

■

Mode The Mode means the filter bandwidth of the ECG channel. The monitor has three modes: diagnosis (DIA), monitoring (MON) and operation (OPR). Under the DIA mode, the filter bandwidth is the widest, and the detailed information of the ECG signal can be got. The more detailed information is helpful to more accurately judge the status of the ECG signal. But when the importation of the detailed information, the environmental noise, such as HF electrotome, 80

may be imported too. The noise mixes with the real ECG signal, so that the ECG signal cannot be distinguished. In order to adapt to the noise interference situation, the Monitor also provides two measurement modes, namely the MON mode and the OPR mode. Under these two modes, narrower bandwidth is adopted to measure and gain smoother signal. The user can make choices according to the exact situations, and the comparing data are as followings: Mode

Auto: The monitor determines the heart rate source depending on the signal quality. ECG takes priority of SpO2. Only when the ECG signal is bad and cannot be analyzed, the heart rate source is SpO2. If the ECG signal becomes normal, the HR source changes to ECG automatically. ● ECG: HR is always calculated from ECG. ● SpO2: If the ECG signal is seriously interfered, you can select SpO2, which means PR will be derived from PLETH waveform. In this case, “PR (SpO2)” is displayed instead of “ECG (I, II, etc.)” while the PR reading is displayed below. The monitor activates pulse beeps instead of heartbeat beeps.

CHAPTER 13:

RESP MONITORING OVERVIEW This Monitor measures out the respiration movement waveform by the ECG cable with the impedance method. This respiration movement waveform is used to calculate the respiration rate and analyse the respiration status. The Monitor can measure three lead respiratory waveforms such as I, II or III lead, of which, the II lead is generally used. Because of the different signal strength, the Monitor provides AUTO and MANUAL modes to adjust the gain. The respiratory waveform will be clear and without distortion if an appropriate gain is adopted.

ELECTRODE PLACEMENT The impedance respiration method of this Monitor is to monitor the patient’s respiration by the impedance variation between the two electrocardiogram electrodes of I, II or III lead. Since the same electrodes are used for ECG and RESP monitoring, the electrode placement is very important. Some patients, due to their clinical condition, expand their chest laterally, causing a negative intrathoracic pressure. In these cases it is better to place the two electrodes used for RESP monitoring laterally in the right axillary and left lateral chest areas, at the maximum point of the breathing movement, to optimize the respiratory waveform.

NOTE ●

● ●

RESP monitoring is not recommended on very active patients, because it will cause false alarms. Place the red and white electrodes diagonally to optimize the respiration waveform. Try to avoid placing the electrodes so the liver area and the ventricles of the heart are in path between the electrodes used for respiration, to avoid cardiac artifact to overlay on the ECG. This is particularly important when monitoring neonate patients.

MONITORING INTERFACE The RESP monitoring displays a RESP waveform in channels area and the measured respiration rate value in parameters area.

RESP CHANNEL

Principal of impedance respiration monitoring The movement of the thorax in the moment of the respiration will cause the variation of the human body’s impedance, the range of the variation is about 0.1 ～3Ω, G3 Monitor immits the human body a safe electric current which is 0.5 ～5mA by using two electrode of the ECGⅡ lead with the 20K ～ 100KΩHZ carrier frequency sinusoidal constant current, and then mesures out the difference of respiration impendace from electrode LL—RA . This difference of the respiration impedance shows the dynamic waveform of respiration Using the impedance respiration method, G3 Monitor can measure out the human body respiration movement waveform by using the electrocardiogram lead line, and this respiration movement waveform can be used to the calculation of the human body respiration rate and the analyse of the human body respiration status.

The G3 Monitor measure three lead respiration waveforms according to the selection such as I, II, III, the II lead is generally used. Because of the different signal strength, the Monitor provides two kinds of gain adjustment functions : automatic adjustment and manual adjustment, it can make the respiration waveform clear and without distortion by adopting appropriate gain. The electrode connection

The impedance respiration method of this Monitor is to monitor the patient’s respiration by the impedance variation between the two electrocardiogram electrodes. The respiration monitoring is realized via the electrocardiogram I, II or III lead and their 86

corresponding electrodes, so no additional electrodes are required, and the installation of the electrode is very important. For some patient, because of their clinical situation, the horizontal expansion of the thoracic cage leads to the negativity thoracic cage internal pressure, under this situation, it is better to put the two respiration electrodes at the central line of the right armpit or the most active area on the left side of the thoracic cage when breathing, so that the optimum respiration wave is gained. We suggest installing five lead electrodes for the respiration monitoring, as shown in Figure 3.4 Notice ①The respiration monitoring is not recommended to be used on the patient who will move or be moved a lot, because it will lead to mis-alarm. ②In order to obtain optimum respiration wave, the white and the red electrodes shall be installled catercorner. Avoid putting the liver and the ventricle on connecting line, which can avoid the false difference produced by the heart coverage or pulsation blood flow, this is very important in the using for neonate.

CHAPTER 15:

NIBP MONITORING OVERVIEW The non-invasive blood pressure (NIBP) module measures blood pressure using the oscillometric method. This monitor can be applied to adult, pediatric and neonate patients. Three measurements are available: manual, auto and continuous. Each mode displays the systolic pressure (SYS), mean arterial pressure (MAP) and diastolic pressure (DIA). ■ Manual: Pressing the NIBP key on the front panel starts a NIBP measurement. ■ Auto: The NIBP measurement is conducted automatically at a preset interval. ■ Continuous: The NIBP measurement is performed as many times as possible in five minutes. Blood Pressure Measurement Principle

NIBP measurement adopts vibration method. The principle is to charge air to blood pressure cuff to the degree that arteries are pressed completely and the blood flowing is blocked. And while the cuff is deflated gradually, the arteries are in the process of utter 90

blocking, gradual loosing and unobstructing. In this process the artery pressure pulsation will generate air oscillating waves in the cuff. Theoretic arithmetic and experiments indicates that oscillating waves have defined correspondence with artery systolic blood pressure, mean blood pressure, and diastolic blood pressure. Hence systolic blood pressure, mean blood pressure, and diastolic blood pressure can be measured by analyzing measurement results and pressure oscillating waves in the cuff.

NIBP Measurement 1. Korotkoff Sound Method, widely-adopted in clinics, is similar to vibration method. But there are many coherent defects in Korotkoff Sound Method. It primarily relies on the coordination between man’s vision and hearing, thus the method is rather subjective and unduplicated. Therefore the results by Korotkoff Sound Method can not be applied to evaluate the results by vibration method.

2. Human arterial blood pressure is a changeable physiological parameter, related with the patient’s emotion, psychological change, posture and position during the measurement. So it should be considered in measurement and evaluation. 3. The vibration measurement bases on the oscillating waves in cuff, so the oscillation from the outside and the movement of the patient’s arm will affect the measurement results. The serious consequence is the failure in the measurement. It needs measuring again. 91

 The noninvasive blood pressure (NIBP) measurement adopts the succussion;  It is applicable to adult, pediatric and neonate.  The measurement mode: manual, automatic and consecutive. Each mode displays systolic blood pressure, mean pressure and diastolic blood pressure.

MONITORING PROCEDURE To perform NIBP measurement on a patient, follow the procedure as below: 1. Power on the monitor. 2. Check the patient type. If the patient type is incorrect, select a correct patient type in Patient Information dialog box. 3. Plug the air hose in the NIBP cuff connector of the monitor. 4. Apply a cuff of proper size to the upper arm or the leg of the patient. 5. Connect the cuff with the air hose. 6. Press the NIBP key on the front panel to start the NIBP measurement.

CUFF SELECTION AND PLACEMENT 1. 2. 3. 4. 5.

Identify the patient limb circumference. Select appropriate cuff; limb circumference is identified on each cuff. Verify the cuff is completely deflated; place cuff around extremity being used and make sure the marking φ matches artery location. Verify the cuff is not wrapped too tightly around the limb. Excessive tightness may cause discoloration or ischemia of the extremities. Make sure that the cuff edge falls within the range of the <-> mark. If it does not, use a larger or smaller cuff that will fit better.

NOTE ●

●

The width of the cuff should be either 40% of the limb circumference (50% for neonates) or 2/3 of the upper arm length. The inflatable part of the cuff should be long enough to circle 50-80% of the limb. The wrong size cuff can cause erroneous readings. If the cuff size is in question, use a larger cuff. The limb chosen for taking the measurement should be placed at the same level as the patient's heart. If this is not possible, use the following method to correct the measurement result: 92

If the cuff is placed higher than the heart level, add 0.75mmHg (0.10 kPa) for each centimeter of difference, or 1.9mmHg (0.25kPa) for each inch of difference.  If it is placed lower than the heart level, deduct 0.75 mmHg (0.10 kPa) for each centimeter of difference, or 1.9mmHg (0.25kPa) for each inch of difference. If you are in doubt about the accuracy of any reading(s), check the patient's vital signs by an alternative method before checking the function of the monitor. 

Use only the specified accessories for monitoring, or it will lead to the malfunction of the Monitor. You must not perform NIBP measurements on patients with sickle-cell disease or under any condition where the skin is damaged or expected to be damaged. For a thrombasthemia patient, it is important to determine whether measurement of the blood pressure shall be done automatically. Ensure that the setting is correctly made when performing measurements on children. Incorrect patient type setting may cause a danger to the patient because adult blood pressure level is higher than children. Before the measurement, you shall confirm your configuration is suitable to the patient (adult, pediatric or neonate). Do not apply the cuff to a limb that has an intravenous infusion or catheter in place. This could cause tissue damage around the catheter when infusion is slowed or blocked during cuff inflation. Auto non-invasive blood pressure measurements performed in long intervals may incur ischemia and neuropathy in the limb wearing the cuff. When monitoring a patient, examine the extremities of the limb frequently for normal color, warmth and sensitivity. If any abnormality is observed, change the position of the cuff on the patient or stop the blood pressure measurements immediately. Make sure the air tubing connecting the blood pressure monitor is not blocked, twisted, or tangled.

MEASUREMENT LIMITATIONS Non-invasive blood pressure measurement uses the oscillometric method of measurement. The monitor detects the regular arterial pressure pulse. In some circumstances when the patient's condition makes it difficult to detect this pulse, the measurement becomes unreliable and the measurement time increases. You should be aware that the following conditions could interfere with 93

the measurement, make the measurement unreliable, prolong the measurement, or even make a measurement impossible. ■ Patient movement: E.g.The patient is moving, shivering or jerking. ■ Cardiac arrhythmia: E.g.The patient's cardiac arrhythmia has caused an irregular heartbeat. ■ Heart-lung machine: E.g. Measurements will be impossible if the patient is connected to a heart-lung machine. ■ Pressure changes: E.g.The patient's blood pressure is changing rapidly over the period of time during which the arterial pressure pulses are being analyzed to obtain the measurement. ■ Severe shock: E.g.If the patient is in severe shock or hypothermia, reduced blood flow to the peripheries will cause reduced pulsation of the arteries. ■ Heart rate extremes: The monitor is unable to perform pressure measurements at a heart rate of less than 15 bpm and greater than 300 bpm.

FUNCTIONS The NIBP monitoring has two functions, one is NIBP measurement, and the other is the 95

venipuncture function.

NIBP MEASUREMENT When the NIBP measurement starts, the Monitor inflates the air into the cuff, and the SYS, DIA and MAP are measured out via the sensor. A measurement process lasts about 40 seconds. There are three NIBP measurement modes, one is manual mode, the other is auto mode, and the third is continuous mode.

Manual mode Select the Auto Manual button in the NIBP menu, if word MANUAL is displayed at the position ⑨, the manual mode is selected. In this mode, a NIBP measurement shall be started manually by pressing the NIBP key on the front panel. Before manual NIBP measurement, the max cuff pressure should be set to a proper value.

Auto mode Select the Auto Manual button in the NIBP menu, if word AUTO is displayed at the position ⑨, the auto mode is selected. In this mode, the monitor periodically starts the NIBP measurement automatically at the preset time interval. The auto mode has two statuses, one is the stay status. In this status, the clock at position ⑧ stays, and the auto measurement has not been started yet. The other status is the running status. In this status, the clock at position ⑧ runs, and the auto measurement has been started. The clock at position ⑧ indicates how much time still remains for the next measurement. In the stay status, press the NIBP key to start the auto measurement. At this time, the clock at position ⑧ begins to run. Switching to the manual mode, then switching back to the auto mode can stop the auto measurement. Pressing the NIBP key during the NIBP measurement can stop the measurement and switch the running status to stay status.

Continuous mode Selecting the Stat Test button in the NIBP menu starts a continuous measurement which is provided for surgical or emergent patient. Its feature is that it continuously measures NIBP for five minutes once it is started, and the measurement mode adopted is simpler than other modes. After five minutes, the monitor restores to the status (auto or manual) before the continuous measurement.

NOTE ●

●

Whether in the auto or manual mode, pressing the NIBP key on the front panel will start a NIBP measurement. Pressing the NIBP key during the NIBP measurement stops the ongoing measurement and deflates the cuff.

VENIPUNCTURE Under the venipuncture mode, the monitor inflates the air into the cuff to a preset pressure, and keeps the pressure during the preset time, then deflates. Select the Venous Puncture button in the NIBP menu, the following dialog box pops up. 96

CHAPTER 16:

TEMP MONITORING TEMPERATURE PROBE INSTALLATION The monitor is able to use two temperature probes simultaneously. Attach the temperature probe to the patient’s body where ought to be measured, to abtain two temperature values and the difference between them. If a disposable temperature probe is used, plug the temperature probe cable in the temperature probe connector, and then connect the temperature probe with the cable; if a reusable temperature probe is used, connect the temperature probe with the temperature probe connector directly.

NOTE ●

The disposable temperature probe is for single patient use only.

WARNING ●

●

Be careful to avoid damaging the temperature probe and cable. When the temperature probe and cable are not in use, shape them into a loose round. If the cable is tangled too tightly or over-bent, mechanical damage may occur. The calibration of the temperature measurement function is desired every year (or as dictated by your Hospital Procedures Policy). If you need to calibrate the temperature measurement function, contact the manufacturer.

CHAPTER 17:

SpO2 MONITORING OVERVIEW SpO2 measurement is based on two principles: Firstly, oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light. Secondly, the volume of arterial blood in tissue changes during the pulse. A monitor determines SpO2 (oxygen saturation) by passing red and infrared light into an arteriolar bed and measuring changes in light absorption during the pulsatile cycle. Red and infrared low-voltage light-emitting diodes (LEDs) in the sensor serve as light sources, a photodiode serves as the photo detector. Because oxyhemoglobin and deoxyhemoglobin differ in light absorption, the amount of red and infrared light absorbed by blood is related to hemoglobin oxygen saturation. To identify the oxygen saturation of arterial hemoglobin, the monitor uses the pulsatile nature of arterial flow. During systole, a new pulse of arterial blood enters the vascular bed, and the blood volume and light absorption increase. During diastole, the blood volume and light absorption reach their lowest point. The monitor bases its SpO 2 measurements on the difference between maximum and minimum absorption (i.e., measurements at systole and diastole). By doing so, it focuses on light absorption by pulsatile arterial blood, eliminating the effects of nonpulsatile absorbers such as tissue, bone, and venous blood. The monitor determines SpO2 and pulse rate by passing two wavelengths of light, one red and one infrared, through body tissue to a photodetector. During measurement, the signal strength resulting from each light source depends on the color and thickness of the body tissue, the probe placement, 105 RED LED AND INFRARED LED LIGHT SOURCES

the intensity of the light sources, and the absorption of the arterial and venous blood (including the time varying effects of the pulse) in the body tissue (Refer to Figure 17-1). 红外线发光二极管

DETECTOR FIGURE 17-1 SpO2 图 8 ：THETORY S p O 2 ％原 OF 理 OPERATION 操作

The monitor processes these signals, separating the time invariant parameters (tissue thickness, skin color, light intensity, and venous blood) from the time variant parameters (arterial volume and SpO2) to identify the pulse rate and calculate oxygen saturation. Oxygen saturation calculations can be performed because oxygen saturated blood predictably absorbs less red light than oxygen depleted blood. The monitor can be used under low perfusion with same accuracy as normal condition.

The monitor measures the patient’s SpO2 and displays: ■ Pulse rate (PR) value in the parameters area. ■ PLETH waveform and pulse intensity (perfusion indicator) in the channels area. ■ Oxygen saturation (SpO2 %) value in the parameters area. As the following figure shows, the perfusion indicator (prorate with the pulse intensity) is located on the left side of the PLETH waveform while the measured SpO2 value on the right. The SpO2 value is displayed by percentage. Besides, the SpO2 label in the parameters area allows you to access the SpO2 menu.

dilution chemicals. ES (Electrosurgery) equipment wire and SpO2 cable must not be tangled up. Carefully route patient cabling to reduce the possibility of patient entanglement or strangulation. Do not use this instrument and the sensors during magnetic resonance imaging (MRI). Induced current could potentially cause burns. The monitor may affect the MRI image, and the MRI unit may affect the accuracy of the oximetry measurements. Do not put the SpO2 sensor on the limb with arterial catheter or venous syringe. Do not perform SpO2 monitoring and NIBP measurements on the same arm simultaneously. Obstruction of blood flow during NIBP measurements may adversely affect the reading of the SpO2 value. Before performing the testing, check the sensor cable. After unplugging the SpO2 sensor cable from the socket, the system shall display the flashing prompt information "Sensor Off" above the PLETH waveform. Prolonged and continuous monitoring may increase the risk of burns at the site of the sensor. It is especially important to check the sensor placement, and ensure proper attachment on neonates and patients of poor perfusion or skin sensitive to light. Check the sensor location every 2–3 hours and move to another location if the skin deteriorates. More frequent examinations may be required for different patients.

NOTE ●

Place the SpO2 sensor cable at the backside of the patient hand. Make sure the fingernail is just opposite to the light emitted from the sensor.

MONITORING PROCEDURE Follow the procedure as below: 1. Power on the monitor. 2. Attach the sensor to the proper site on the patient. 3. Plug the connector of the sensor extension cable into the SpO2 connector on monitor. The process of SpO2 plethysmogram measurement is generally the same. But the SpO2 sensor selection and placement depend on the patient type. When choosing a site for a sensor, refer to the directions for that sensor.

MEASUREMENT LIMITATIONS If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by an alternate method. Then check the instrument for proper function. Inaccurate measurements may be caused by: ■ Incorrect sensor application or use; ■ Placement of a sensor on the same extremity with a blood pressure cuff, arterial catheter, or intravascular line; ■ Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight (exposure to excessive illumination can be 107

corrected by covering the sensor with a dark material); ■ Excessive patient motion; ■ Venous pulsations; ■ Intravascular dyes such as indocyanine green or methylene blue; ■ Defibrillation; Other physiological conditions or medical procedures that may interfere with the monitor’s measurements include significant levels of dysfunctional hemoglobin, low perfusion, and dark pigment. Loss of pulse signal can occur in the following situations: ■ The sensor is too tight; ■ A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor attached; ■ There is arterial occlusion proximal to the sensor. Select an appropriate sensor, apply it as directed, and observe all warnings and cautions presented in the directions for use accompanying the sensor. Clean and remove any substances such as nail polish from the application site. Periodically check to ensure that the sensor remains properly positioned on the patient. If patient movement presents a problem, try one or more of the following remedies to correct the problem. ■ Verify that the sensor is properly and securely applied. ■ Move the sensor to a less active site.

CHAPTER 18: IBP

MONITORING IBP CHANNELS The monitor provides two channels to measure the invasive blood pressure (IBP, including systolic, diastolic and mean pressures), and displays two channels of waveforms and two parameters. The two channels of waveforms are displayed in a same or different waveform area, differentiated by color. When the two curves overlapped, the curve color will be the color of channel 2. The figure below is the channels displayed in different waveform area: 110

0 mmHg The bottom horizontal line indicates the location of zero pressure. If a curve dot is displayed higher than this line, it means the pressure of this dot is positive; accordingly, the pressure of the dot, which is lower than this line, is negative. The top horizontal line indicates the maximum pressure of current display gain. The curve line where its pressure is higher than the maximum pressure will be clipped and becomes a section of horizontal line. The height of the waveforms relates to the pressure. And the ratio between height and pressure is specified. Maximum value and Minimum value are listed in the following table: Maximum value on screen

PRECAUTIONS WARNING ●

●

● ●

Use only the IBP transducer specified in this manual. Disposable IBP transducers should not be reused. Parts and accessories used must meet the safety requirements of the medical electrical equipment standards. Avoid conductive connection to the applied part likely to degrade safety. When the monitor is used with high frequency surgical equipment, do not allow the transducer and the cable contact the high frequency surgical equipment to prevent the patient from burning caused by leakage current.

MONITORING PROCEDURE 1. Plug the pressure cable into the IBP connector on the monitor and power on the monitor. 2. Prepare the pressure line and transducer by flushing the system with normal saline solution. Make sure the tubing and transducer system is free of air bubbles.

NOTE ●

In case of any entrapped air in the pressure system, re-fill the system with normal saline.

Label It has the same function as the Label button in the IBP parameter menu. Selecting this button switches the label of this channel.

Zero In the first time we select this button, the corresponding channel will perform zero process. And selecting this button again will terminate the zeroing. The system will treat the detected absolute pressure value as the relative zero point. This zero point affects both the pressure values and the 114

waveforms of the channel. Zeroing procedure: 1. Disconnect the transducer from the patient. 2. Adjust the 3-way stopcock to close the channel leading to the patient. The transducer is open to the atmosphere through the stopcock. 3. Select the Zero button in the IBP channel menu to start zeroing.

NOTE ●

●

●

●

The zeroing funciton is noneffective in sensor off status, it is effective only when the sensor is connected to the monitor. Position the transducer at the same level with the patient’s heart, approximately midaxillary line. Perform the pressure zeroing when the monitor is powered on and at measuring intervals (at least once per day). The zeroing should also be conducted once the transducer cable or catheter is changed. Ensure the catheter is static. In the catheter static status, the zeroing will be completed soon.

Gain Mode This button is to select the display gain mode for the channel. The gain mode switches between Auto and Manual when selecting this button. This function is disabled if the channel wasn’t zeroed.

Adjust Gain If the gain mode of the channel is Manual, we can use this button to increase/decrease display gain. The clockwise for decrease, whereas for increase. This operation zooms in the waveform in vertical direction. This function is also disabled if the channel wasn’t zeroed.

MAINTENANCE AND CLEANING WARNING ●

Before cleaning the transducer, make sure the transducer is disconnected from the monitor, or the monitor is powered off and disconnected from AC power.

CLEANING OF IBP TRANSDUCER After the IBP monitoring operation is completed, remove the tubing and the dome from the transducer and wipe the transducer diaphragm with water. To clean the transducer and the cable, wipe them using soap or the detergents listed below: ■ Cetylcide ■ Wavicide-01 ■ Wescodyne ■ Cidex ■ Lysol ■ Vesphene Do not immerse the connector in any liquid. After cleaning, dry the transducer thoroughly before storing. Slight discoloration or temporary increase of surface 115

stickiness of the cable should not be considered abnormal. If it is necessary to remove the adhesive tape residue from the transducer cable, the double seal tape remover is recommended; use the remover with special caution to minimize the damage to the cable. Acetone, Alcohol, Ammonia and Chloroform, or other strong solvents are not recommended because they are harmful to the vinyl cabling if used for a long time.

NOTE ● ●

The disposable transducers or domes must not be reused. To avoid contamination, the disposable transducers or domes must be reclaimed or disposed of properly, complying with the local laws.

STERILIZATION Chemical Solution Sterilization After finishing the cleaning, select an effective sterilant for chemical solution sterilization of the operating room equipment. Buffered glutaraldehyde (e.g. Cidex or Hospisept) is recommended. Do not use quaternary cationic detergents such as zephiran chloride. If the whole unit is to be sterilized, immerse the transducer but not the electrical connector into the sterilant for the recommended sterilizing period. Ensure that the dome has been removed. Then rinse all transducer parts except the electrical connector with sterilized water or saline. The transducer must be thoroughly dried before storing.

Gas Sterilization For more complete asepsis, use gas sterilization. The transducer should be completely dry after cleaning. When ethylene oxide gas is used as the gas disinfectant, follow the operating instructions provided by the manufacturer of the gas disinfectant.

NOTE ●

The disinfectant temperature must not exceed 70°C (158°F). Plastics in the pressure transducer may deform or melt above this temperature.

CHAPTER 19:

CO2 MONITORING INTRODUCTION CO2 monitoring is to monitor the respiration of patient by detecting the concentration of CO 2 generated during respiration. The maximum concentration of CO2 at the end of exhalation is called End-Tidal CO2 (EtCO2). The minimum concentration of CO2 at the end of inspiration is called Fractional Inspiratory CO2 (FiCO2). CO2 is generated by cells in the body during metabolizing, and is breathed out via breath system. The concentration of CO2 breathed out from lung reflects directly the situation of metabolizing and breathe system. If the concentration of CO 2 is high, it means that metabolizing is excited, such as blood poisoning or acute fever. If the concentration of CO2 is low, it is commonly because the output ability of heart is weak, or the heart stop beating, or the lung soak for the flux of blood is low or oxygen it carried is not enough. Monitoring CO2 is used to warn the doctor of the abnormal of breathe and metabolizing for hocused patient. The concentration of CO2 is represented as a pressure level, with mmHg, kPa or % as its unit. Generally, the acceptable value is 38mmHg (5.1kPa or 5%) when air pressure is 760mmHg. The concentration of CO2 varies very fast from 0% to 5% normally. To detect the concentration of CO2 accurately, the monitor has to be very sensitive.

MONITORING PROCEDURE Follow the procedure specified below to monitor the CO2. 1. Plug the dehydration vase into its receptacle, then push its bottom carefully to its position, shown as the figure below: Water trap receptacle Sampling line

Connect one end of the sampling line to the dehydration vase. Connect the other end of the sampling line to the patient. Power on the monitor. Enables the displaying of CO2 channel via the Format Setup button in the Display menu. Select the Start Pump button in the CO2 channel menu to start air pump. The CO2 monitoring starts. 117

NOTE ●

●

To monitor the CO2, the CO2 channel and the air pump must be enabled. If the monitor is in default settings, these two items must be reset. When there is no CO2 monitoring, disables the CO2 channel or air pump to prolong its service life.

119

MAINTENANCE AND CLEANING In case of an exception in the sampling system of the CO2 module, check for entanglement of the sampling line. If the sampling line is not entangled, remove the dehydration vase. In this situation, if the dehydration vase is not blocked, the sampling line must have been blocked, and you must replace it with a new one. If the dehydration vase has been blocked, you should replace it with a new dehydration vase.

WARNING ● ● ●

●

The sampling line is disposable, must not re-sterilize or reuse it. Do not press or limit the sampling line. The dehydration vase is used to collect water drops condensed in the sampling airway and prevent water drops from entering the module. When the collected water reaches to a certain amount, remove the water to avoid blocking the airway. In the long-term use, dust or other substances may lower the air permeability of the filter material in the dehydration vase and may block the airway. In this situation, the dehydration vase must be replaced.

NOTE ●

The sampling line must be recycled or disposed of properly, complying with the local laws.

120

a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the equipment is used exceeds the applicable RF compliance level above, the equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the equipment. b. Over the frequency ranges 150kHz to 80MHz, field strengths should be less than 3V/m.
