dc.description.abstract The isobaric (oxygen window) principle of decompression embodies the assumption that the pressure of inert gas in tissues and blood stream should at no time exceed ambient pressure during decompression. Essentially in the capillaries there is an exchange of oxygen and inert gas. The fall in oxygen pressure in the capillaries creates 'a partial pressure vacancy' designated as the oxygen window. The size of the window regulates the rate of diffusion of inert gas into the blood stream and its subsequent transport and elimination in the lungs. The higher the oxygen pressure in the gasmixture breathed up to 1500 mm Hg (2 Atm), the greater the transport of inert gas. In current saturation diving operations, the rate of ascent during decompression has been in the range of 10 to 15 minutes per foot. This rate is consistent with an oxygen window that varies from 230 to 360 mm Hg, and with the slowest desaturating tissue with a half-time (helium) of 60 minutes. There appears to be no basis for the assumption that there are half-times for the slowest tissue (helium) as long as 300 minutes, and that inert gas during decompression is transported in a state of supersaturation devoid of bubbles. en
