Scope: Determine the required minimum oxygen concentration to be breathed prior to@ during@ and after a loss of cabin pressurization@ and Determine recommended means necessary to provide the required oxygen concentrations. CONCLUSIONS: To prevent impairment of consciousness caused by hypoxia after decompression oxygen must be used as follows: A. Above 24@000 and up to 40@000 feet the system must provide@ in accordance with Figure 1: (1) An increased minimum oxygen concentration prior to a decompression@ (2) A schedule of increased oxygen concentration with increase in cabin altitude@ (3) 100% oxygen at an altitude not higher than 24@000 feet@ and (4) Safety pressure to begin simultaneously with delivery of 100% oxygen. B. Between 40@000 and 45@000 feet the system must provide@ in addition to the above@ (1) Delivery of 100% oxygen under positive pressure@ increasing with altitude to maintain no less than the equivalent of 40@000 feet. C. When cabin altitude can not exceed 25@000 feet (1) No change in present requirements.
