8.5.9 Enabling Smart Lead Off
When the smart lead off function is set on and there is a “lead off” in the lead that has an
ECG waveform in filter mode and notch status, if another lead is available, this available lead
automatically becomes that lead. The system will re-calculate HR and analyze and detect
arrhythmia. When the “lead off” condition is corrected, the leads are automatically switched
back.
To switch on/off the smart lead off function, select [Others >>] from the [ECG Setup] menu;
select [Smart Lead Off] and toggle between [On] and [Off] from the popup menu.
8.5.10 Setting the Alarm Level for ECG Lead Off Alarms
Select [Alarm Setup >>] from the [User Maintenance] menu. You can set [ECGLeadOff
Lev.] from the popup menu.
8.5.11 Adjusting QRS Volume
QRS sounds are produced based on the alarm source. To adjust the QRS volume, select
[Others >>] from the [ECG Setup] menu; select [QRS Volume] from the popup menu and
select the appropriate setting. When valid SpO
2
measured value is available, the system
adjusts the pitch tone of QRS sound based on the SpO
2
value.
8.5.12 About the Defibrillator Synchronization
If a defibrillator is connected, a defibrillator synchronization pulse (100 ms, +5V) is
outputted through the Multifunctional Connector every time when the patient monitor detects
an R-wave.
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 the [Filter] is set to [Diagnostic].
z After defibrillation is finished, select the filter mode as required.
