Spirometric Performance of Aircrew Using the Molecular Sieve Oxygen Generator in High Performance Flight.

Abstract

A comparative evaluation of the pulmonary effects of pure oxygen (LOX) versus the product of the molecular sieve oxygen generator (MSOG) was conducted by eight aircrewmen in an EA-6B aircraft during normal and high g flight maneuvers. Significant reductions in vital capacity and expiratory flow rates immediately following high g flights were observed only in those subjects breathing 100% oxygen. Spirometric values following nonaerobatic flight, however, were not significantly altered by either gas system. Within the limited scope of this study, it appears that the small amount of inert gases present in the MSOG product offers a measurable level of protection against high g absorptional atelectasis in aviators.
