Scientists at the Duke Center for Hyperbaric Medicine and Environmental Physiology are conducting research on the Prebreathe Reduction Program for the National Aeronautical and Space Administration (NASA). Healthy, physically fit male and female, 25-60 years of age, are invited to volunteer.
The goal of the NASA prebreathe program is to develop oxygen-breathing procedures to help astronauts, incorporating light exercise to allow them to be ready for spacewalking faster than with standard resting oxygen prebreathe protocols.
“We need healthy individuals who are reasonably fit,” noted Dr. Neal Pollock, a research physiologist and principal investigator on the project. Persons maintaining a regular schedule of two to three hours of aerobic exercise per week would likely qualify.
The study requires one-half day of fitness testing — including an aerobic capacity test on a cycle ergometer — and orientation to the study protocol. Participation in the study is then scheduled at least three days after the screening.
The study day involves light exercise while breathing oxygen and then simulated travel in the hypobaric chamber to a reduced pressure equivalent to what astronauts experience during a spacewalk. The simulated spacewalk includes light exercise similar to what astronauts might perform.
