Abstract
The ambient pressure of the environment of an individual within a vessel is varied between an upper and lower pressure value by providing the vessel with a mass of gas sufficient to fill at least a substantial part of the vessel, and varying the quantity of liquid, primarily water, in the vessel in order to cause the pressure therein to vary correspondingly between the upper and lower values.
