In the recent developement in mechanical ventilatory support, HFV has advocated by a few investigators. HFV has the following characteristics: 1) ventilatory frequency with about 3 times or more higher than that of conventional IPPV: 2) small tidal volume, usually approaching volume of the calculated dead space VD : and 3) positive airway pressure and subambient intra pleural pressure throughout the entire respiratory cycle.
Twelve thoracotomies were performed under the respiratory control of HFV with 60 cycle per minute, and the following results were obtained : 1) arterial blood gas was almost within the normal range; mean PaO2 107 torr (58-188), PaCO2 44 torr (29-77), pH 7.37 (7.23-7.50) and BE-2.41 mEq/l ( -4.0- 4.0) even at the point of the worst PaO2 and 2) intrathoracic handling during operation was very easy and smooth because of the minimal shift of lung volume and no atelectasis of untouched part even the operated lobe.
