5.2.2 New alarm scheme
This scheme is based on assigning priority levels to alarm situations.
Priorities correspond to the present danger level and the time before a
potential hazard occurs, according to the following table:
The signals and tone sequences corresponding to the various priorities
are assigned uniformly to a range of medical device groups: As a result,
all dialysis devices will, as a rule, generate a uniform set of alarm
signals.
Basic assignment The assignments of alarm condition, priority, and device response are
defined as follows:
High priority:
Red flashing operating status indicator and repeated tone sequence of
10 beeps.
Medium priority:
Yellow flashing operating status indicator and repeated tone sequence
of 3 beeps.
Low priority:
Yellow steady operating status indicator and repeated tone sequence of
2 beeps.
The system also offers the option of providing information ("Warning"):
Green flashing operating status indicator with repeated tone and
isolated information tones.
In this way, each alarm scenario is assigned a priority that defines the
alarm response of the device.
5.3 High-priority alarm conditions
Since critical alarm situations can cause the machine to be placed in
Safe Mode (halting treatment), alarms with high priority are only
triggered in exceptional cases, where a potential hazardous condition
persists even following alarm response.
