개흉술 마취시 기능성 환기법에 관한 임상적 고찰

Abstract

Many of the lung cancer. bronchiectasis. mediastinal tumor. lung abscess and pulmonary tuberculosis are treated occasionally by the surgical operation and most of the cases are performed in the lateral position. Several studies were reported about the effect of lateral position on the pulmonary ventilation and perfusion and about the preventive methods of hypoxia which may be issued in the lateral position. Recently we have studied the influence of the changes of tidal volume and frequency at the same minute volume in the lateral position on the AaDO,. In spite of changes of tidal volume and frequency, we could not find any differences in the arterial oxygenation and the CO, elimination at the same minute volume.
