Alarm Categories and Levels
Alarm Categories:
The oximeter’s alarms can be classified into two categories: physiological alarms and
technical alarms.
1. Physiological alarms
Physiological alarms, also called patient status alarms, are triggered by a monitored
parameter value that violates set alarm limits or an abnormal patient condition.
2. Technical alarms
Technical alarms, also called system status alarms, are triggered by a device
malfunction or a patient data distortion due to improper operation or system problems.
Alarm Levels
By severity, the oximeter’s alarms levels can be classified into three categories: high level
alarms, medium level alarms and low level alarms.
1. High level alarms
Indicate that the patient is in a life threatening situation and an emergency treatment is
demanded.
2. Medium level alarms
The patient’s vital signs appear abnormal or the oximeter system status appears
abnormal, indicate that prompt operator response is required.
3. Low level alarms
The patient’s vital signs appear abnormal or the oximeter system status appears
abnormal, indicate that operator awareness is required.
The levels for both technical alarms and physiological alarms are predefined and can not
be changed by user.
