Airway Pressures during Positive-pressure Ventilation with Superimposed Oscillations

open access: yesUpsala Journal of Medical Sciences, 1990
This study was undertaken to determine whether oscillations superimposed on a regular ventilatory pattern influence the arterial blood gases and pH and the airway pressures at adequate alveolar ventilation at the onset of inhibition of inspiratory activity. The peak, mean and end-expiratory airway pressures were therefore measured at inhibition of this
