Review Of High Altitude Aviation Preoxygenation / Denitrogenization Procedures And Draft Pressure Schedule For Open-Cockpit Balloon Flight To 65,000 Feet, Cameron M. Smith

Anthropology Faculty Publications and Presentations

Aviation Decompression Sickness (DCS) is a well-known and well documented phenomenon in which a spectrum of physiological and cognitive symptoms result from aircrew exposures to altitudes greater than roughly 10,000 feet, where atmospheric pressures and the partial pressure of oxygen are significantly lower than the mean pressures in which the human body has evolved. The main factors involved in the likelihood of DCS are (a) exposure altitude, (b) exposure time at altitude, (c) preoxygenation / denitrogenization duration and procedure and (d) exercise at the exposure altitude. Mitigation of DCS is largely achieved by (a) preoxygenation / denitrogenization before flight, (b) …
