Alarms
Alarms triggered by a vital sign that appears abnormal or by technical problems of the equipment, are indicated
to you by visual and audible alarm indications.
WARNING
•
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.
•
If the equipment is connected to a CMS, remote suspension, inhibition, silence and reset of
monitoring alarms via the CMS may cause a potential hazard. For details, refer to the operator’s
manual of the CMS.
•
Do not rely exclusively on the audible alarm system for monitoring. Adjustment of alarm volume to a
low level may result in a hazard to the patient. Always make sure that the audio alarm volume level is
adequate in your care environment. Always keep the patient under close surveillance.
4.1 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 the 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.
4.2 Alarm Levels
By severity, alarms can be classified into three categories: high level alarms, medium level alarms and low level
alarms.
Physiological alarms Technical alarms
High level Indicate that your patient is in a life
threatening situation, such as
Asystole, Vfib/Vtac and so forth, and
an emergency treatment is
demanded. Indicate a severe device malfunction or an improper
operation, which may result that the equipment cannot
detect critical patient status or may cause therapy failed, and
thus threaten the patient’s life, such as low battery.
Medium level Indicate that your patient’s vital signs
appear abnormal and an immediate
treatment is required. Indicate a device malfunction or an improper operation,
which may not threaten the patient’s life but may
compromise patient monitoring or therapy.
Low level Indicate that you patient’s vital signs
appear abnormal and an immediate
treatment may be required. Indicate a device malfunction or an improper operation,
which may compromise a certain function but will not
threaten the patient’s life.
