Anthropology Faculty Publications and Presentations

Pacific Spaceflight's first proof-of concept pressure garment, the Mark I (model Gagarin), was worn by a test subject in a pressure chamber to test stable maintenance of blood oxygenation, body temperature and suit pressure. While breathing normal air at a simulated altitude of 4,000m (c.13,000ft) the test subject's blood oxygenation was 90%, a figure expected for an altitude of 2,590m (8,500ft). The test subject's blood oxygenation climbed back to normal (96%-95%) as the hypobaric chamber was repressurized to sea level figures. The garment successfully maintained the test subject in the first half of the Blood Oxygenation Disassociation Range of …
