NASA Exercise Prebreathe Study
Sponsor: Duke University
Summary
This study evaluates oxygen prebreathe protocols and exercise conditions to reduce risk of decompression sickness during simulated extravehicular activity. Healthy adult volunteers will undergo oxygen prebreathe followed by hypobaric chamber exposure with monitoring for symptoms and ultrasound detection of bubbles.
