According to the severity of the alarm, the physiological alarms of the monitor can be divided
into high level, medium level and low level.
High level 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 level alarms
The patient's physiological signs are abnormal, and appropriate measures or treatment should
be taken immediately;
Or although it won’t endanger the patient’s life, the mechanical failure or misoperation of the
monitor will affect the normal monitoring of key physiological parameters.
Low level alarms
The patient's physiological signs are abnormal, and appropriate measures or treatment may
need to be taken;
Or certain monitoring function is invalid due to mechanical failure or misoperation, but it
won’t endanger the patient’s life.
The levels of all technical alarms and some physiological alarms have been set in the monitor
at the factory and cannot be modified by the user. The levels of some physiological alarms
can be modified.
