Abstract:

Results of tests conducted indicate that a gain in survival time during underwater escape involving the full pressure suit can be achieved by rebreathing from the suit proper provided the pilot is not in a head-down position. This extension in duration of time of useful consciousness is over and above that afforded by use of the emergency oxygen system, if available. DuringANY UNDERWATER ESCAPE INVOLVING THE FULL PRESSURE SUIT, THE HELMET VISOR SHOULD BE KEPT CLOSED AND SEALED AND THE EMERGENCY OXYGEN SYSTEM ACTIVATED. If the emergency oxygen system is inoperable or depleted, a furth r gain in survival time can b achieved by rebreathing from the suit proper. The duration of the time of useful consciousness when rebreathing from the full pressure suit underwater is a function of the position of the suit controller and carbon dioxide build-up. The findings reported here apply to submersion in water at any depth while wearing the full pressure suit. Author
