||Incidence of decompression sickness in hypoxia training with and without 30-min O2 prebreathe
||Jan. 2003, Vol.74, No.1, p.56-61. Illus. 16 ref.
||Naval aircrew are required to participate in hypoxia familiarization training. This training is considered high-risk due to the potential for barotrauma and decompression sickness (DCS). Prior analysis of the DCS in U.S. Navy hypobaric chambers revealed a significantly higher incidence among inside observers (IOs) than among students. In response to these reports, all IOs are required to de-nitrogenate by breathing 100% oxygen for 30min prior to altitude exposure. However, there have been no reports validating the efficacy of this measure. This study examined the incidence of altitude DCS during exposures to simulated altitudes of 25,000ft (25k) and 35,000ft (35k) in IOs and students, some who pre-breathed oxygen and some who did not. Results indicate that a 30-min pre-breathe prior to altitude exposure reduces the risk of DCS.
