PHYSIOLOGIC EFFECTS OF EXPOSURE TO INCREASED OXYGEN TENSION AT 5 P.S.I.A.,
Abstract
Data were obtained during two 14-day experiments in the USAF SAM two-man space cabin simulator relative to the physiologic factors in atmosphere selection. Both experiments were conducted at a simulated altitude of 27,000 feet (258 mm. Hg) and a PO2 of 243 mm. Hg. Emphasis was placed on arterial and alveolar PO2 and PCO2, chest x-rays, and vital capacity, all determined at the experimental altitude and atmosphere. The atmosphere, in general, was well tolerated by all 4 test subjects. No atelectasis was made evident by x-ray or by changes in vital capacity. Although vital capacity was reduced an average of 2.9%, this was not felt to be indicative of atelectasis. Arterial PO2 was slightly lowered but, again, it did not indicate a significant increase in the normal physiologic shunting of blood. (Author)
