Alarms
APNEA, APNEA xx bpm
When the time since the start of the last breath is longer than the set Apnea Interval, the APNEA
alarm is generated. When an Apnea alarm occurs, the ventilator will enter Apnea Backup ventilation
mode. For more information on Apnea Backup mode, see Chapter 4 - Ventilation Modes, Apnea
Backup. For more information on the variable Apnea Interval, see Chapter 10 - Extended Features.
When an APNEA alarm occurs:
• Any inspiration in progress is terminated.
• The ventilator changes to Apnea Backup ventilation.
• The APNEA xx bpm backup ventilation breath rate is displayed.
• Control displays used while in Apnea Backup mode are illuminated and all other control displays
are dimmed.
• The audible alarm is sounded.
While in Apnea Backup mode, the alarm will continue to sound and the alarm message and breath
rate will be flashed in the display window. Apnea backup mode will continue until the operator resets
the alarm or the patient triggers 2 consecutive breaths.
When the APNEA alarm is reset by 2 consecutive triggered breaths:
• Apnea Backup Ventilation terminates and the ventilator returns to the previous mode.
• The APNEA alarm message remains flashing in the window but the breath rate is no longer
displayed.
• Control displays used in the selected ventilation mode are illuminated and all other control
displays are dimmed.
• The audible alarm is silenced.
To reset the APNEA alarm and exit Apnea Backup ventilation:
1) Push the Silence Reset button twice.
