Normal max inspiratory pressure
WebThe main controls in HFOV are mean airway pressure, oscillatory pressure amplitude, bias flow, frequency, and inspiratory time. With piston-driven oscillators, piston-centering is an additional control mechanism. Mean airway pressure determines the mean lung volume of the lung. Oscillatory amplitude is the total change in pressure around the ...
