Telemetry Transmitter User Manual Alarm Management
Chapter 11 Alarm Management
The contents related to this chapter are all operated on MFM-CMS.
11.1 Overview
Alarms, triggered by a physiological sign that appears abnormal or by technical problems of the
telemetry transmitter, are sent to the MFM-CMS by the telemetry transmitters and then indicated
to the users by the MFM-CMS. Alarms coming from the telemetry transmitters are displayed in
the patient sectors and in the single bed view window.
The alarm and prompts coming from the MFM-CMS system are displayed in the system
information area on the upper screen.
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.
NOTE:
The alarm signal will be delayed for no more than 5 seconds.
11.1.1 Physiological Alarms
If one or several physiological parameters of the currently monitored patient exceed the
predefined alarm limit, the telemetry transmitter will give an alarm, and this type of alarm is
called physiological alarms. It includes parameter alarm and arrhythmia alarm. About the detailed
alarm information, please refer to the Section Chapter 12 Alarm Information.
Physiological information alarm arouses the doctors’ attention by means of visual and audible
methods specified in harmonized international standard. Visual method is realized basically by
the way of lightening or flicking of the color light. Audible method is realized by the sound for
different levels.
Physiological alarms are implemented by alarm limits, which define a range in which a certain
physiological parameter is considered to be in the normal status. When a parameter value is
beyond the range, the system will consider it to be in an abnormal status and consequently give
an alarm.
11.1.2 Technical Alarms
If one or several technical status of the device is in abnormal status, the telemetry transmitter will
send an alarm to MFM-CMS. And this type of alarm is called technical alarms. Technical alarms
can’t be disabled. Technical alarms of telemetry transmitter refer to alarms other than
physiological alarms, including hardware failure, communication error, lead off, etc. About the
detailed alarm information, please refer to Section Chapter 12 Alarm Information.
