6 Alarm
Alarm means that the monitor prompts the medical staff through sound and light when the abnormal changes in vital signs are
monitored or the monitor has a failure or is unable to monitor the patient successfully.
WARNING
In any single region (e.g. ICU), it has potential danger if the same or similar devices use different alarm setup.
-
After setting, the alarm and other parameters of the monitor won’t be lost when the system is power off, unless modified
manually. Connect the power again and turn on the monitor, it will resume normal working, and the alarm and other
parameters remain unchanged.

6.1 Alarm types
According to the nature of the alarm, the alarms of the monitor can be divided into physiological alarms, technical alarms and
prompt messages.
Physiological alarms
A physiological alarm is usually triggered when a physiological parameter of the patient exceeds the alarm limit or the patient
has physiological abnormalities. The information of physiological alarm is displayed in the physiological alarm area on top of
the screen.
Technical alarms
Technical alarm is also known as a system error message, which is caused by improper operation or system failure resulting in
system malfunction or monitoring result distorted. The information of technical alarm is displayed in the technical alarm area
on top of the screen.
Prompt messages
Strictly speaking, the prompt messages are not alarms. The monitor also will display some information associated with system
status in addition to the physiological alarms and technical alarms, and generally such information do not involve the patient's
vital signs. The prompt messages generally appear in the technical alarm area and parameters area.
6.2 Alarm condition priorities
According to the severity of the alarm conditions, the physiological alarms of the monitor can be divided into high priority, medium
priority and low priority.
High priority alarms
The patient is in critical condition that is life-threatening, and should be immediately rescued, or the monitor has a serious
mechanical failure or malfunction, causing it unable to detect the patient's critical state and endangering the patient’s life.
Medium priority alarms
