8.11. Calibrating ECG
The ECG signal may be inaccurate due to hardware or software problems. As a result,
the ECG waveform amplitude becomes greater or smaller. In that case, you need to
calibrate the ECG module. To do so, follow this procedure:
1. Select
ECG parameter area or waveform area, set 【 Filter Mode 】 to
【Diagnose】.
2. Select 【 Main Menu 】 quick keyfrom 【 System 】 column to select
【Maintenance】input maintenance passwordEnter.
3. Select【Module】submenu【ECG】submenu.
4. Select【Calibrate】, the square wave signal will appear on the screen to
compare the amplitude of the square wave with the scale. The error range
should be within 5%. The ECG calibration must be completed by the
maintenance personnel.
8.12. Defibrillation Synchronization
The module provides an analog out connector to output defibrillation synchronization
signal. If a defibrillator is connected, it receives a synchronization pulse (100 ms, +5 V)
through the analog out connector each time an R-wave is detected.
The steps to set defibrillation synchronization are as follows:
1. Select 【 Main Menu 】 quick keyfrom 【 System 】 column to select
【Maintenance】input maintenance passwordEnter.
2. Select【Module】submenu【Auxiliary Output】submenu.
3. Set the defibrillation synchronization signal as needed.
CAUTION：
Improper use of a defibrillator may cause injury to the patient. The operator
should determine whether to perform defibrillation or not according to the
patient’s condition.
According to AAMI specifications the peak of the synchronized defibrillator
