G Glossary

AC Power
Alternating current.
Alarm Pause
The audible and visual alarms cease and the symbol appears. The symbol will remain until the
cause of the alarm is addressed. For example, when the ventilator is running on internal battery,
the AC Disconnection alarm may be paused, and the alarm paused symbol will appear until the
device is plugged into AC. The paused alarm will be captured in the alarm log screen and can be
reactivated.
Alarm Reset
Used only for the High Pressure alarm, this function resets the visual alarm message.
Apnea
The absence of breathing or a breathing pattern capable of supporting an individual's respiratory
needs.
AI - Apnea Index
The Apnea index is average number of apnea events per hour of ventilation. It is based on the
Apnea Alarm.
Apnea Time
Time allowed between breath starts before APNEA alarm occurs when no patient effort is
detected.
Assist/Control
In Assist/Control mode, the ventilator delivers an assisted breath of a set volume or set pressure
when the patient's breathing effort creates a flow or pressure drop that is greater than the
SENSITIVITY setting. In absence of patient breathing effort, the ventilator will deliver a controlled
breath of the set volume or pressure. (Does not apply in PSV/CPAP mode).
Assisted Breath
A volume or pressure breath triggered by the patient but then controlled and terminated by the
ventilator.
Audio Pause
Pauses the audible alarm for 60 seconds at a time and shows the symbol; often referred to as
"Alarm Silence."
Back Up Rate
Rate of control cycles in PSV or SIMV modes during apnea phase.
