Figure 1From: 0989. Accuracy of delivered airway pressure during proportional assist ventilation +. A bench studyRepresentative tracings of measured airway pressure (Pawmeas) and theoretical airway pressure (PawTh) with progressive increases in rate (RR) and PEEPi. Black lines: PawTh wareforms. Blue lines: Pawmeas waveforms. Inspiratory trigger = 5 L.min; PEEP = 0 cmH2O; gain = 60%; Pmus = 10 cmH2O; Resistance = 20 cmH2O/L/s and compliance = 60 mL/cmH2O.Back to article page
