Technical Alarm Messages
This section lists technical alarms, their default priority, indication on alarm reset, and the actions that can be
taken when an alarm occurs.
Technical alarms give different alarm indicators when the alarm system is reset. In this section we classify the
technical alarms into three categories for easy clarification:
■
A: technical alarms are cleared. The monitor gives no alarm indications.
■
B: technical alarms are changed to the prompt messages.
■
C: the alarm is silenced and a √ appears before the alarm message.
In the following tables we will use A, B, and C to refer to the indications on alarm reset.

Cause and solution
ECG Noisy
Low/Prompt
A
The ECG signal is noisy. Check for any possible
sources of signal noise around the cable and
electrode, and check the patient for excessive
motion.
ECG Amplitude Too Small
Low
C
The ECG amplitude does not reach the detected
threshold. Check for any possible source of
interference around the cable and electrode.
ECG Lead Off
Low
B
The electrode has become detached from the
patient or the lead wire has become
disconnected from the adapter cable. Check the
connections of the electrodes and leadwires.
ECG XX Lead Off
Low
B
The electrode has become detached from the
patient or the lead wire has become
disconnected from the adapter cable. Check the
connections of the electrodes and leadwires.
ECG Signal Invalid
Low
A
Patient skin impedance is too high. Check ECG
electrode application.
ECG Learning
Prompt
/
ECG learning is manually or automatically
triggered.
Cannot Analyze QT
Prompt
/
