Alarms
Alarms, triggered by a vital sign that appears abnormal or by technical problems of the
monitor, are indicated to the user by visual and audible alarm indications.
WARNING

A potential hazard can exist if different alarm presets are used for the same or
similar equipment in any single area, e.g. an intensive care unit or cardiac
operating room.

If your equipment is connected to a CMS, remote suspension, inhibition, silence
and reset of monitor alarms via the CMS may cause a potential hazard. For
details, refer to the CMS’s instructions for use.
6.1 Alarm Categories
By nature, the equipment’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. The
physiological alarms occur only in Monitor mode.
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 mechanical
problems.
Apart from the physiological and technical alarm messages, the monitor shows some
messages telling the system status or patient status. System related messages are
displayed in system message area; parameter related messages are displayed in
respective parameter message area.
