Technical Alarm Messages
Alarm message Default priority Indication 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 High, Med, or
Low,
configurable
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 High, Med, or
Low,
configurable
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 / /
Alarm message Default priority Indication on
alarm reset
Cause and solution
Resp Interference Prompt / The respiration circuit is disturbed. Check for any
possible sources of signal noise.
Electrode Poor Contact Prompt / Check the electrode application. Reposition or
replace the electrodes if necessary.
Alarm message Default priority Indication on
alarm reset
Cause and solution
SpO2 Sensor Off Adjustable B The SpO
2
sensor has become detached from the
patient or the module. Check the sensor
connection. If the alarm persists, replace the
sensor.
SpO2 No Sensor Low A The SpO
2
extension cable is detached from the
SpO
2
module, or the SpO
2
sensor is detached
from the SpO
2
extension cable. Check the SpO
2
cable and the sensor connection. If the alarm
persists, replace the sensor.
SpO2 Excess Light Low C Ambient light is too strong. Move the sensor to a
place with lower level of ambient light or cover
the sensor to minimize the ambient light.
