This study was attempted to observe the possible effects of open chest and the decubitus position on blood gas values during controlled ventilation. We used a volume-type ventilator to maintain regular tidal volume throughout the operation. A total of 51 cases which underwent open chest surgery between 1979 and 1981 in Department of Anesthesiology in Kyungpook National University Hospital were selected. PaO_2, PaCO_2, pH and MAP were measured at ten minutes after induction (control group), decubitus position (ducubitus group) and chest was opened (open chest group). The PaO_2 value in open chest and decubitus group revealed a tendency of elevation compared with the control group. The PaCO_2 value in open chest revealed no remarkable change compared with the control group. The pH in open chest and decubitus group showed a tendency to increase compared with the control group. The MAP showed a tendency to decrease in open chest & decubitus groups and decreased gradually. From the above results, MAP showed a gradual decrease but the increase of pH and PaO_2, suggested the inclination of resiratory alkalosis due to hyperventilation during volume controlled ventilation anesthesia.
