Many of the problems of exposing man to a high pressure environment depend overtly on the properties of gases in the gaseous phase--such as the various squeezes, voice distortion, thermal effects of helium, density effects, and decompression sickness. Others relate directly to the properties of a specific gas--such as oxygen or carbon dioxide toxicity and nitrogen narcosis. Still another set of phenomena appear to be related to pressure per se, or to changes in pressure. These are the subject of this chapter. The distinction is an arbitrary one, since both hyperbaric arthralgia and the high pressure nervous syndrome may, in fact, be gas-related problems and there is no doubt that the nature of the gas present plays a secondary role however, for convenience of presentation, the authors treat them as independent of the nature of the gas.
