Evidence for Increased Intrathoracic Fluid Volume in Man at High Altitude,
Abstract
To determine if subclinical pulmonary edema occurs commonly at high altitude, 25 young male soldiers participated in a strenuous, 72 h field exercise at low altitude (200 to 875 m) and in a similar exercise one week later at high altitude (3000 to 4300 m). At 0, 36, and 72 h of each phase the subjects were given a physical examination, a chest radiograph was taken, and the following measurements were made: total lung capacity, forced vital capacity, residual volume, closing capacity, slope of phase III of the nitrogen washout curve, transthoracic electrical impedance, and the quasi-static relationship between transpulmonary pressure and lung volume (PV curve).
