Influence of the steepness of the ramp on the phenomenon. A stepwise increase of the ramp, set on the Oxylog 3000™, resulted in an increase of the amplitude of the airway pressure oscillations (Paw-amplitude) as well as in an increase in the airway pressure overshoot (Paw-overshoot), defined as the peak airway pressure minus the upper pressure limit.
