9.9 Latching Alarms
The latching setting for physiological alarms defines how alarm indicators behave if you do not reset the alarms.
■ If you do not “latch” physiological alarms, their alarm indications disappear when the alarm condition ends.
■ If you “latch” physiological alarms, all visual and audible alarm indications remain until you reset the alarms.
For latched alarms the time when the alarm is last triggered is displayed behind the alarm message.
You can separately latch visual indications or simultaneously latch the visual and the audible indications.
■ When visual indications are latched, visual indications, including alarm lamp, alarm message and its
background remain when the alarm condition ends and the time when the alarm last triggered is displayed
behind the alarm message.
■ When audible indications are latched, the monitor issues alarm sounds when the alarm condition ends.
The alarm latch settings is password protected. For more information, see 27.4.3The Latching Tab.
• Changing alarm priority may affect the latching status of corresponding alarm. Determine if you
need to reset the alarm latching status if you changed the alarm priority.
• When the alarm system is reset, latched physiological alarms are cleared.
