Detection and Prevention of G-Induced Regional Atelectasis, Edema, and Hypoperfusion.
Abstract
These investigations were concerned with the evaluation of pulmonary circulation and the distribution of ventilation in response to maneuvering acceleration. In order to study the response of +Gz protection by the anti-G suit, respiratory maneuvers, and pharmacologic agents, it was necessary to improve existing methods and to develop new ones--both in anesthetized dogs and in human volunteers. To standardize noninvasive tests of the pulmonary circulation and distribution of ventilation, invasive studies were necessarily performed on anesthetized animals for comparison. One of the studies which dealt with the action of anti-G suits led to the hypothesis that anti-G suits would be more efficient if they inflated from below, upward (rather than from the abdominal bladder, downward, as in the standard USAF anti-G suit).
