8.5.6 Switching Defibrillator Synchronization On/Off
As defibrillator synchronization, analog output and nurse call share the same signal output
port, you need to set the port for defibrillator synchronization before getting the monitor and
defibrillator synchronized. To set the port for defibrillator synchronization:
1. In the main menu, Select [Maintenance >>]→[User Maintenance >>]→enter the
required password.
2. Select [Device Setup >>] to access the [Device Setup] menu.
3. Select [Auxiliary Output] and then [Defib. Sync].
To switch defibrillator synchronization on or off:
1. Select the ECG parameter window and then select [Others >>].
2. Select [Defib. Sync] and toggle between [On] and [Off].
If a defibrillator is connected, a defibrillator synchronization pulse (100 ms, +5V) is
outputted through the Defib. Sync connector every time when the patient monitor detects an
R-wave. When [Defib. Sync] is set on, the message [Defib Sync On] is displayed in the
technical alarm area.
WARNING
z Improper use of a defibrillator may cause injury to the patient. The user should
determine whether to perform defibrillation or not according to the patient’s
condition.
z Before defibrillation, the user must ensure both defibrillator and monitor has
passed the system test and can be safely used jointly.
z Before defibrillation, make sure that [Defib. Sync] is set to [On] and the [Filter] is
set to [Diagnostic].
z After defibrillation is finished, set [Defib. Sync] to [Off] and select the filter mode
as required.
