Mixed Gas Hypoxia Training in Low Pressure Chambers

The objective of this proposal is to improve the safety and effectiveness of hypoxia recognition and recovery training for mask-off aircrew using the 9A9 low pressure chamber or other suitable enclosure to provide mixed gas hypoxia training. This proposal demonstrates the feasibility of providing hypoxia recognition and recovery training using normalbaric mixed gases or a combination of mixed gas and pressure altitudes of 8-10,000 ft. for mask-off hypoxia training. This training would be provided using the existing 9A9 hypobaric chambers at the Naval Aviation Survival Training Centers. If only normalbaric mixed gas training was required an alternative enclosure could be utilized.
