3.2 Connection 3.2.1 ECG Cable/Lead Wires Connection ECG measurement is to collect the ECG signal via the ECG electrodes. Electrode connects the patient and the lead wires and/or ECG cable. The lead wires and/or cable connect to the monitor. The locations of the electrodes are very important for obtaining accurate ECG signals. 1. Connect the cable to the connector marked with the “ECG" icon on the signal input panel. 2. Select electrodes to be used. Use only one type of electrode on the same patient to avoid variations in electrical resistance. For ECG monitoring, it is strongly recommended to use silver/silver chloride electrodes. When dissimilar metals are used for different electrodes, the electrodes may be subject to large offset potentials due to polarization. Using dissimilar metals may also increase recovery time after defibrillation. 3. Prepare the electrode sites according to the electrode manufacturer’s instructions. 4. Skin clean ¾
Clean and scrap skin to ensure low sensor impedance if necessary. Mild soap and Water is recommended as a skin cleanser. Note: If alcohol is used as cleanser, it is recommended to have 30-second dry time for a better connection.

Safety Instructions for ECG Monitoring 0
Patient Monitor can only be equipped with ECG cable and/or lead wires provided by our company; using ECG cable and/or lead wires supplied by other companies may cause improper performance or poor protection while using defibrillator.
0
Using the same type of qualified and authorized electrodes which should be within its effective life on the same patient. If any side-effect such as allergic or stimulus skin is found, the measurement should be stopped at once. It is prohibited to apply the electrode to the patient with lesion and body putrescence.
0
To the patient with pacemaker, due to that this device has been designed to provide function of pacemaker pulse inhibition for heart beat identification, normally the pacemaker pulse is not counted in heart rate measurement and calculation, but when the pulse width of the pacemaker pulse is larger than 2ms, the pacemaker pulse inhibition may not be fully effective. In order to reduce this possibility, observe the ECG waveforms on the screen carefully and do NOT rely entirely on the heart rate display and alarm system of this monitor when monitoring this kind of patients. Keep pacemaker patient under close surveillance.
0
The improper connection with electrosurgical unit may not only cause burns, but also damage the monitor or arouse deviations of measurement. You can take some steps to avoid this situation, such as do NOT use small ECG electrodes, choosing the position which is far away from the estimated Hertzian waves route, using larger electrosurgical return electrodes and connecting them with the patient properly.
Electric parts of electrodes, leads and cable are forbidden to contact any other conductive parts (including ground).
Patient Monitor can resist against defibrillator and electrosurgical unit. Readings may be inaccurate for a short time after or during using defibrillator or electrosurgical unit.
Transient caused by cable circuitry blocks while monitoring may be similar to the real heartbeat waveform, as a result resistance heart rate alarm rings. If the electrodes and cable are located in proper places according to this manual’s instructions and the instructions for using electrode, the chance of this transient occurrence will be decreased.
ECG cable and/or lead wires may be damaged while using defibrillator. If the cable and/or lead wires are used again, please do the functional check firstly.
When the monitor is inoperable due to overload of ECG or saturation of any part of the amplifier, it will prompt “Lead off” to remind operator.
The user should ensure that no predictable hazard will be caused by the summation of leakage currents when several item of monitor are interconnected.
When plugging or unplugging the ECG cable, be sure to hold the head of the connector and pull it out.
3.2.2 Cuff Connection for Blood Pressure Measurement 1. Connect the tube with cuff to the connector marked with “NIBP” icon on the signal input panel. 2. Unfold the cuff and wrap it around the patient’s upper arm. Requirements of the cuff: 1) Appropriate cuff should be selected according to the age and arm circumference of the subject. Its width should be 2/3 of the length of the upper arm. The inflatable part should be long enough to permit wrapping appropriately 80% of the limb. See the table below for the dimensions: Note: the appropriate cuff should be selected according to the age and arm circumference of the patient.

Pressure Accuracy Verification Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside the device. Technician or equipment manager should do pressure accuracy verification every half year or year in order to check if the pressure measurement still conforms to the requirement of product performance. If the deviation is beyond the declared specification, it is permitted to return it to factory for repair or calibration. Before verification, please connect the monitor to a precision pressure meter as the reference equipment like a mercury pressure meter
-9-
User manual for Patient Monitor
Figure 3.7 Connection of Pressure Accuracy Verification Fixture Mode 1: Automatic inflation for the pressure accuracy verification At this mode, the monitor can activate the inflation, so the pressure will increase automatically until it exceeds the limit value specified in table A. This pressure limit value depends on the patient type selection as shown in table A: Adult
240mmHg
Pediatric
200mmHg
Neonate
120mmHg Table A
During the inflation, the Monitor will close the deflating valve, and the pressure value will be shown during the process. If there is no manual deflation operation, the pressure will persist until deflation by manual operation, so it is necessary to use a manual valve for doing adequate deflation in several steps to verify the pressure accuracy in the full scale of measurement range. Mode 2: Manual inflation for the pressure accuracy verification. At this mode, the pressure should be increased manually by a pumping balloon, and the verification can be done by applying different pressure value manually. If the increased pressure exceeds the given limit as shown in table B, the Monitor will deflate automatically because of over-pressure protection. Adult
300mmHg
Pediatric
240mmHg
Neonate
140mmHg
Table B After the verification, do press the button again to return to normal working mode, then continue other operation, or the NIBP key will be invalid.
¾
Pressure accuracy verification must be operated by technician or equipment manager. Doctor or nurse is not allowed to do the verification, it is very dangerous especially when the pressure cuff is still on patients.
Air Leakage Check -10-
User manual for Patient Monitor
In order to avoid significant error of blood pressure measurement or even no measurement result caused by air leakage in the pneumatic system including the cuff during measuring, it is recommended to check if there is leak in the pneumatic system as well.
Please remove the cuff from patient while performing the leakage check.
Safety Instructions for NIBP Measurement 0 When taking the blood pressure measurement on a Pediatric or Neonate patient, do NOT operate in the Adult mode. The high inflation pressure may cause lesion or even body putrescence. Even though the monitor can identify the cuff type so it will stop inflation and indicate "wrong cuff" when taking the blood pressure measurement for a pediatric or neonate in the "adult" patient type setting. The user (doctor or nurse) should pay more attention to select the correct patient type. 0 It is recommended to take the blood pressure measurement manually. 0 NIBP monitoring is prohibited to those who have severe hemorrhagic tendency or with sickle cell disease, or partial bleeding will appear. 0 Do NOT bind NIBP cuff on limbs with transfusion tube or intubations or skin lesion area, otherwise, damages may be caused to the limbs. 0 If the patient is moving or suffering tremble, hyperkinesia or arrhythmia, it may cause the inflation time of inflatable balloon endures longer, which may not only prolong the NIBP measurement time, but also result in the body wrapped by the cuff is troubled by purpura, hypoxemia and neuralgia because of the friction. 0 Before the measurement is carried out, select an appropriate monitoring mode depending on the patient type (adult, pediatric or neonate). 0 It is prohibited to wrap the cuff to a limb with skin lesion 0 DO NOT take blood pressure measurement from a limb receiving ongoing transfusion or intubations. Because it may damage the limb tissue around the intubation if the transfusion becomes slower or blocked during the cuff inflation. 0 The windpipe which connects the cuff and monitor should be straightway without any tangle. When an adult subject is monitored, the machine may fail in giving the blood pressure measure if the pediatric mode is selected. Prior to use of the cuff, empty the cuff until there is no residual air inside it to ensure accurate measurement. Do NOT twist the cuff tube or put heavy things on it. When unplugging the cuff, hold the head of the connector and pull it out. The NIBP measurement will not be affected when the monitor is connected to the patient on whom the electrosurgical device such as defibrillator or electrosurgical knife with high frequency is being used. The appearance of arrhythmia results in irregular heart beat which may affect the accuracy of NIBP measurement data. It is recommended to take the NIBP measurement again at this situation. The Blood pressure measurements determined with this device are equivalent to those obtained by a trained observer using the cuff/stethoscope auscultatory method, within the limits prescribed by the American National Standard, Manual, electronic, or automated sphygmomanometers. The symbol indicates that the cable and accessories are designed to have special protection against electric shocks, and is defibrillator proof.

Connect the SpO2 probe to the connector marked with “SpO2” icon on the signal input panel. When unplugging the probe, be sure to hold the head of the connector and pull it out. 2. Insert one finger (index finger is preferred, but middle or ring finger with proper nail length is possible as well) into the probe according to the finger mark on the probe, shown as below.
Figure 3.8A Demonstration of Adult/Pediatric SpO2 Finger Clip Sensor (A) With the upper and lower jaws open, place a finger evenly on the base of the clip. Push the finger tip against the stop so that it is over the sensor window. (B) Spread open the rear tabs of the sensor to provide even force over the length of the pads. (C) The sensor should be oriented in such a way that the cable is positioned along the top of the hand.

Figure 3.8B Demonstration of Adult SpO2 Finger Rubber Sensor (A) Hold the sensor with its opening towards the patient’s finger, the sensor should be oriented in such a way that the sensor side with a finger tip sign is positioned on the top. (B) Insert the patient’s finger into the sensor until the fingernail tip rests against the stop at the end of the sensor. Adjust the finger to be placed evenly on the middle base of the sensor. Direct the cable along the top of the patient’s hand. Apply adhesive tape to secure the cable if necessary. When selecting a SpO2 probe or sensor, do consider the patient’s category, adequacy of perfusion, availability of probe site and anticipated monitoring duration. Use only SpO2 probes provided by our company with this monitor. Read the following table for SpO2 probe information. SpO2 Probe

Figure 3.8C Neonate SpO2 sensor placement Some factors may affect the accuracy of saturation measurements. Such factors include: excessive patient motion, fingernail polish, use of intravascular dyes, excessive light, poorly perfused finger, extreme finger sizes or improper placement of the sensor. High ambient light sources such as surgical lights (especially those with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, and direct sunlight can interfere with the performance of a SpO2 sensor. -13-
User manual for Patient Monitor
To prevent interference from ambient light, ensure that the sensor is properly applied, and cover the sensor site with opaque material if necessary. Failure to take this action in high ambient light conditions may result in inaccurate measurements. If patient movement presents a problem, verify that the sensor is properly and securely applied; move the sensor to a less active site; use an adhesive sensor that tolerates some patient motion; or use a new sensor with fresh adhesive backing. For reusable sensors, follow the sensor directions for use, cleaning and reuse. For single-patient use sensors, use a new sensor for each patient. Caution: Do not disinfect any SpO2 sensor by irradiation, steaming, or ethylene oxide. Safety Introductions for SpO2 Monitoring 0 Continuous use of fingertip SpO2 sensor may result in discomfort or pain, especially for those patients with microcirculatory problem. It is recommended that the sensor should NOT be applied to the same site for over two hours, please inspect the monitoring site every 1~2 hours for skin integrity, and change the measuring site periodically if necessary. 0 SpO2 measuring site must be examined more carefully for some special patient. Do NOT place the SpO2 sensor on the finger with edema or fragile tissue. 0 Avoid placing the SpO2 sensor on the same extremity with an arterial catheter, blood pressure cuff, or intravascular infusion line, otherwise the blood flow could be interrupted by the cuff or the circulatory condition could make low blood perfusion so that would result in on pulse found or loss of pulse during SpO2 monitoring and further cause false alarm. 0 Do not apply tape to secure the sensor in place or to tape it shut; venous pulsation may lead to inaccurate oxygen saturation measurements. For disposal SpO2 sensor, If the sterile packaging is damaged, do not use it any more. Check the SpO2 sensor and cable before use. Do NOT use the damaged SpO2 sensor. Before each use, surface-clean sensor and cable with a soft gauze pad by saturating it with a solution such as 70% isopropyl alcohol. If low-level disinfection is required, use a 1:10 bleach solution. When the temperature of SpO2 sensor is abnormal, do not use it any more. Please do not allow the cable to be twisted or bended. Please do not use nail polisher or other cosmetic product on the nail. The fingernail should be of normal length.
The SpO2 sensor cannot be immerged into water, liquor or cleanser completely, because the sensor has no capability to resist the harmful ingress water. Carefully route cables to reduce the possibility of patient entanglement or strangulation. Do not use the sensor or other oximetry sensors during MRI scanning.
