4.3 Alarm Levels

In terms of severity, the device's alarm levels can be classified into three categories: high level
alarms, medium level alarms and low level alarms.
1. High level alarms
A high level alarm intensively warns the operator of a high priority alarm condition which
requires immediate operator response. Failure to respond to the cause of the alarm condition
is likely to result in death or irreversible injury of the patient.
2. Medium level alarms
A medium level alarm warns the operator of a medium priority alarm condition which
requires prompt operator response. Failure to respond to the cause of the alarm condition is
likely to result in reversible injury of the patient.
3. Low level alarms
A low level alarm reminds the operator of a low priority alarm condition which requires
response. And the response time for a low priority alarm condition can be greater than that for
a medium priority alarm condition. Failure to respond to the cause of the alarm condition is
likely to result in discomfort or reversible minor injury of the patient.
The high/medium/low-level alarms are indicated by the system in following different ways:
