Summary

The aims of this proposal are to test current USN procedures for adjusting decompression procedures during air diving at 8,000 and 10,000 ft altitude and to provide a decompression algorithm for no-stop dives to 100 feet of sea water (fsw) at 10,000 and 12,000 ft altitude using enriched O2 (PO2=1.3 ATM). Additionally, the experiments will determine whether a period of hyperbaric hyperoxia, such as would be experienced during a dive at altitude, reverses altitude acclimatization, resulting in a return of acute mountain sickness (AMS) symptoms.

Conditions

  • Decompression Sickness
  • Acute Mountain Sickness

Interventions

OTHER

Pressure

Subjects undergo altitude exposure, diving exposure, and return to altitude. Altitudes: 8,000, 10,000, 12,000, or 15,000 feet Dives: 60 or 100 feet of sea water

OTHER

Breathing Gas

Subjects will breathe air, 35% Oxygen, Balance Nitrogen, or 100% Oxygen during the diving exposure
