title: [Effect of 120-day antiorthostatic hypokinesia on gas exchange and pulmonary circulation in humans].
abstract: Parameters of gas exchange and pulmonary circulation were measured in five healthy test subjects during 120-day head-down tilt test and early recovery. During the first half of the bed rest study CO2 tension in arterial blood increased significantly. During the second half of the study oxygen and carbon dioxide tension decreased significantly. The mechanisms of these changes are discussed.
