6.4 Latching Alarms
As described in 4.4.2 Alarm Setup, the parameter alarm type can be set to either
LATCH or UNLATCH.
If the parameter alarm type is set to LATCH, before or during the occurence of a
parameter alarm, the alarm message will be latched even if the initial alarm
condition has ceased. The alarm messsage continues to be displayed, but the
alarming modes change as follows:
îš„ The measured parameter value and the upper or lower parameter limits stop
flashing.
îš„ The generated time of the alarm is displayed behind the alarm message in the
physiological alarms area.
If the parameter alarm type is set to UNLATCH, the monitor stops giving any
indication for this alarm when the initial alarm condition has ceased.
