The physiological alarms are classified into “Latching” and “Non-latching”.
Non-latching alarms:

parameter disappears, the system will not make any prompt for this alarm of
this parameter.
Latching alarms: Even if the condition that caused the physiological alarm
disappears, the alarm signal will still be “Latched”, and the time of the last
triggering of the alarm will be displayed behind the alarm information in the
information area.
You can choose to individually lock the visual signal or simultaneously lock
the visual and audible signals.
For visual latching, after the alarm condition disappears, the visual signal of
the alarm, including the alarm light, the alarm information and the
background color remain unchanged, and the alarm information text is
followed by the time of last triggering the alarm.

condition disappears.

the medium priority alarm and the high priority alarm will also be
latched simultaneously.
