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.
