- Abstract
- Phase IV volumes of the single-breath nitrogen washout curve were measured as an index of pulmonary interstitial fluid volume at ground level and after exposure to altitude. In a 4-hr exposure to 16,000 ft in a decompression chamber, no significant change was found in the phase IV volume or the phase IV/vital capacity ratio, in five subjects. In 12 subjects exposed to 17,500 ft on Mount Logan, no significant change was seen in phase IV volumes after 1 week. It is concluded that no measurable increase in the pulmonary interstitial fluid volume, as detected by this technique, occurred with altitude exposure at the time intervals in which it was measured.
