19 Alarm information
This chapter lists some important physiological and technical alarm information, and some alarms are not necessarily listed.
Note that in this chapter: P column indicates the default alarm priority: H indicates high priority, M indicates middle priority, L
indicates low priority, and “*” indicates priority set by the user.
Corresponding countermeasures are listed for each alarm message. If you operate in accordance with the countermeasures but the
problem persists, contact your service personnel.

Causes and countermeasures
ECG
HR Too High
M*
HR value is higher than the upper alarm limit or lower than the
lower alarm limit. Check the patient's physiological condition, and
check if the patient category and alarm limit settings are
appropriate for the patient.
HR Too Low
PVCS Too High
M*
PVCs value is higher than the upper alarm limit or lower than the
lower alarm limit. Check the patient's physiological condition, and
check if the patient category and alarm limit settings are
appropriate for the patient.
Asystole
H
The patient has arrhythmia. Check the patient's condition,
electrodes, cables and lead wires.

Pacemaker Not work
H
ECG Signal weak
H
The patient ECG signal is too weak, and the system can’t analyze.
Check the patient's condition, electrodes, cables and leads.
ST-I Too High
M*
ST value is higher than the upper alarm limit or lower than the
lower alarm limit. Check the patient’s physiological condition,
and check if the patient category and alarm limit settings are
appropriate for the patient.

ST-II Too High
ST-II Too Low
ST-III Too High
ST-III Too Low
Resp
RR Too High
M*
Patient PR value is higher than the upper alarm limit or lower
than the lower alarm limit. Check the patient's physiological
condition, and check if the patient category and alarm limit
settings are appropriate for the patient.
RR Too Low
Apnea(RESP)
H
The patient’s respiratory signal is too weak, and the system can’t
analyze. Check the patient's condition, electrodes, cables and
leads.
RESP ARTIFACT
H*
Respiration heartbeat interference
Temp
T1 Too High
M*
T1/T2 value is higher than the upper alarm limit or lower than the
lower alarm limit. Check the patient's physiological condition, and
check if the patient category and alarm limit settings are
appropriate for the patient.
T1 Too Low
T2 Too High
T2 Too Low
TD Too High
TD value is higher than the upper alarm limit or lower than the
lower alarm limit. Check the patient's physiological condition, and
check if the patient category and alarm limit settings are
appropriate for the patient.
