Medical Considerations in the Selection of Space Cabin Atmospheres
In the past, the pressure of engineering commitments involved in the development of spacecraft required that decisions on space cabin atmospheres be made early, often before the physiological tolerance to unnatural gaseous environments could be determined. Selection has been based primarily on engineering grounds with the burden of proof on the physiologist that the proposed environments could not be tolerated. While this approach has been adequate in the past, it will have to be modified for the longer and more hazardous missions projected for the future.
