AirPAP
CPAP — Continuous Positive Airway Pressure
A single, constant pressure that keeps the upper airway open throughout the breath.
Waveform
How it works
- A therapy mode that continuously applies a single set positive airway pressure throughout the breathing cycle.
- Every breath is started and ended spontaneously by the patient.
- The set pressure level is held through both the inspiratory and expiratory phases.
- No mandatory breaths or additional inspiratory pressure support are delivered by the device.
- The applied positive pressure helps keep the upper airway open.
Physiological basis
By creating a pneumatic splint in the upper airway, CPAP prevents pharyngeal collapse. It raises functional residual capacity, lowers upper-airway resistance and keeps the airway open during sleep. The work of breathing is reduced while alveolar stability is preserved.
Adjustable parameters 4
CPAP Pressure
Continuous positive airway pressure level.
Additional Pressure
Extra pressure applied on top of the therapy pressure in non-automatic modes, to respond to the patient’s events.
Sigh
Applies 1.5× the inspiratory pressure once every 20 breaths.
RESFLEX
Comfort feature that eases the pressure at the start of exhalation.
