| Abstract |
The relation between hydrostatic pressure and gas-exchange symmetry was studied by exposing 895 rats to pressures of 20, 30 and 40ata until equilibrium. A 2-step, single-stage decompression was conducted to a point where 50% of the animals displayed signs of decompression sickness. By varying the time of the single decompression stop, the time necessary for the animals to reestablish equilibrium following the initial decompression was determined. Gas uptake is much faster than gas elimination during decompression. In addition, it is suggested that gas elimination is an inverse function of saturation exposure pressure. There may be an optimum time to spend at a decompression stop for maximising the rate of gas elimination. |
