Figure 4From: Inspiratory oscillatory flow with a portable ventilator: a bench studyInfluence of the test lung – resistance. Stepwise increase of the resistance on the LS800™ lung simulator 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 peak airway pressure minus the upper pressure limit.Back to article page
