For example, when ‗R on T‘ alarms, the ‗V-Trigeminy‘ on the same link will not alarm even if it takes place; if
‗Extreme-Tachy‘alarm is triggered, 'R on T' will be replaced due to its lower priority even if they belong to two
different links. If ‗VR‘ is triggered later, the two alarms will be given simultaneously without affecting the other
because they have the same priority on different links. Once ‗VFib/VTac‘ or other high-level arrhythmia alarm is
triggered, all alarms on the other three links will be alternated.

Arrhythmia Forbidden Time
Arrhythmia alarm is instantaneous, thus it is possible that users will neglect some alarm information. In order
to avoid this, we designed the system to handle mid-/low-level arrhythmia alarm differently from other
physiological alarms: once arrhythmia alarm is triggered, both the same type of alarm condition will not be
repeatedly triggered and the alarms of lower priorities is disabled at the preset time. We refer to this period as
to the Arrhythmia Forbidden Time.
As illustrated in Figure 6.12, this series of monitors categorize the mid-/low-arrhythmia into the First
Forbidden Time and the Second Forbidden Time.
Attention

Prohibition period of High level arrhythmia alarm default must be manually eliminated in the alarm
line, but you can press [SILENCE] to end the prohibition period of high level arrhythmia alarm. The
full prohibition in [Alarm Config>>] is defaulted on, When it is set as off, prohibition period ends
automatically if it detects ECG signal.

Users can set the forbid time in [User Maintain>>]-[Alarm Config>>]-[1st Forbid Time] / [2nd Forbid
Time].
During the forbidden time of a mid-/low-level alarm when a higher-priority alarm is triggered, the forbidden time
of this alarm is instantly over and the system enters the forbidden time for higher priorities.
During the forbidden time of a mid-/low-level alarm when a higher-priority alarm not belonging to any alarm link
is triggered:

The monitor will maintain its current alarm condition if no updating operation is conducted.

The forbidden time is instantly over when the [PAUSE] is pressed or the alarm switch is stopped. In case this
alarm is still valid when the alarm pausing is activated, the forbidden time will be recalculated from its first
triggered moment following the end of the alarm pausing.

The forbidden time is not affected when the [SILENCE] is pressed.

In case this alarm is terminated when the [SILENCE] is pressed, the alarm information will be instantly
cleared when the [SILENCE] is pressed. During the forbidden time, the same alarm or an alarm of
lower priority is not triggered for a second time.

In case this alarm is not terminated when the [SILENCE] is pressed, the alarm will be muted when the
[SILENCE] is pressed: audio alarm disappears and a narrative alarm is added with a '√' in the front, and
if this alarm terminates during this forbidden time, narrative alarm disappears instantly when the alarm
terminates. The same alarm or the alarm of lower priorities can only be triggered again when the
forbidden time has elapsed.
