Gender Not a Risk for Altitude Decompression Sickness Risk
Abstract
We conducted 25 altitude chamber decompression exposure profiles incorporating both genders in a prospective attempt to clarify the role of gender in DCS susceptibility. METHODS. The 291 human subjects were exposed (961 subject-exposures) to simulated altitude for up to 8 h, using zero to 4 h of preoxygenation. Subjects breathed 100% oxygen, rested or performed mild or strenuous exercise while decompressed, and were monitored for precordial venous gas emboli (VUE) and DCS symptoms. RESULTS. No differences (P--0.24) in DCS incidence were observed between males (49.5%) and females (45.3%). Higher DCS incidence (P <0.001) was observed in the heaviest males, females with the highest body fat, and in subjects with the highest body mass indices and lowest levels of fitness. CONCLUSION. No differences in altitude DCS incidence were observed between males and females under our test conditions. No apparent need exists for changes in procedures, training, or equipment to enhance protection from DCS based on gender.
