Notes and Analysis of NASA Shuttle and ISS Prebreathe Options with Special Reference to 'Campout' Prebreathe

摘要

The International Space Station (ISS) will operate at 14.7 psi, requiring crews to 'campout' in the airlock at 10.2 psi. The constraints associated with campout (crew isolation, oxygen usage, and waste management), provided the rationale to develop a prebreathe protocol. This presentation offers analyses of NASA shuttle and prebreathe operations, specifically the campout prebreathe protocol. Portions of the demonstration highlight decompression stress during extravehicular activities in microgravity and models of exercise prebreathe.
