Alarms
Alarms, triggered by a vital sign that appears abnormal or by technical problems of the equipment, are indicated to the
user by visual and audible alarm indications.
WARNING
z
A potential hazard exists if different alarm presets are used for the same or similar device in any single area,
e.g. an intensive care unit or cardiac operating room.
5.1 Alarm Categories
By nature, the equipment’s alarms can be classified into three categories: physiological alarms, technical alarms and
prompt messages.
1. Physiological alarms
Physiological alarms, also called patient status alarms, are triggered by a monitored parameter value that violates
set alarm limits or by an abnormal patient condition. Physiological alarm messages are displayed in the
physiological alarm area. In AED mode, no physiological alarm will be presented.
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 failure. Technical alarm messages are displayed in the technical alarm area.
3. Prompt messages
As a matter of fact, prompt messages are not alarm messages. Apart from the physiological and technical alarms,
the equipment also shows some messages indicating system status. Messages of this kind are usually displayed in
the prompt area. Therapy-related prompts are shown in corresponding information area. Some special prompts are
shown in dialog boxes.
