6.10 Latching Alarms
The latching setting for physiological alarms defines how alarm indicators behave when
you do not acknowledge them.

If an alarm is latched, alarm indications remain presented even though alarm
conditions end, except that:

The parameter reading and violated alarm limit stop flashing.

The time when the alarm is last triggered is displayed behind the alarm
message.

If an alarm is not latched, the alarm indications disappear as soon as the alarm
conditions end.
To latch a physiological alarm,
1. Select [ Main ]
→
[ Maintenance >> ]
→
[ User Settings >> ]
→
Enter required password
→
Select [ Ok ] and then access [ User Settings ] menu.
2. Select [ Alarm Setup >> ].
3. Set [ Alarm Latch ] to [ High only ], [ High&Med ], [ All ] or [ Off ].

[ High only ]: only high priority alarms are latched;

[ Hi&Med ]: both high priority alarms and mediate priority alarms are latched;

[ All ]: all alarms are latched; and

[ Off ]: no alarm will be latched.
Only the unacknowledged physiological alarm can be latched. The latched alarms will be
cleared when the monitor enters alarm reset state.
NOTE

Changing of alarm priority may affect the latching status of corresponding
alarm. Please determine if you need to reset the latching status for the specific
alarm when you have changed its alarm priority.
