Apnea Backup ventilation
Apnea Backup ventilation is available in Assist Control (A/C), SIMV, APRV/BiPhasic
and CPAP/PSV modes.
Apnea Backup in Assist Control or SIMV
The set mandatory breath rate or the Apnea Interval setting (whichever provides the
highest respiratory rate) determines the apnea backup rate.
When the Apnea Interval setting (found in the Alarm Limits window) determines the backup
rate, the ventilator continues to ventilate at this rate until the apnea has been resolved. All
other controls for apnea ventilation in Assist Control (A/C) and SIMV are the current active
primary controls.
Apnea ventilation ends when a patient initiates a spontaneous breath, a manual breath
is delivered or the rate control is increased above the Apnea Interval setting.
