Ventilatory characteristics in mechanically ventilated patients during manual hyperventilation for chest physiotherapy
We measured the tidal volumes and peak inflation pressures generated during manual hyperventilation for chest physiotherapy in 25 adult ventilated patients. The average tidal volume ranged from 711 to 1511 ml, with a mean (SD) of 1120 (274) ml. There was a negative correlation (p
