7.1 Alarm types
According to the nature of the alarm, the alarms of the monitor can be divided into physio-
logical alarms, technical alarms, alarm reminder signal 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.
Alarm Reminder Signal
Alarm Reminder Signal is periodic signal that reminds the operator that the alarm system
is in an alarm signal inactivation for both physiological alarm conditions and technical
alarm conditions.
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.
7.2 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.
High priority alarms
The patient is in critical condition that is life-threatening, and should be immediately res-
cued, 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
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 me-
chanical failure or deactivation of the monitor will affect the normal monitoring of key
physiological parameters.
Low priority alarms
The certain monitoring function is invalid due to mechanical failure or deactivation, but it
won’t endanger the patient’s life.
The levels of some physiological alarms can be modified. But, the priority of all technical
alarms and some physiological alarms have been set in the monitor at the factory and cannot
be modified by the user.
