5. Effects of microgravity on tissue perfusion and the efficacy of astronaut denitrogenation for EVA

Author

Gerth, Wayne A, Vann, Richard D, Leatherman, Nelson E, and Feezor, Michael D

Subjects
Aerospace Medicine
Abstract

A potentially flight-applicable, breath-by-breath method for measuring N2 elimination from human subjects breathing 100 percent O2 for 2-3 hr periods has been developed. The present report describes this development with particular emphasis on required methodological accuracy and its achievement in view of certain properties of mass spectrometer performance. A method for the breath-by-breath analysis of errors in measured N2 elimination profiles is also described.
