Application of asymmetric physiologically inert gas kinetics in diving decompression calculation / 军事医学

ABSTRACT

Objective To explore the application of asymmetric kinetics of physiological inert gases in diving decompression algorithm.Methods Considering that the actual desaturation in the human body was slower than the saturation process,the kinetic equations of different saturation and desaturation rate of inert gases were constructed with piecewise functions on the basis of the original single exponential kinetic equation.The results were compared other adjustment methods.Results With the application of asymmetric kinetics, the time at each decompression stop was prolonged for an approximately equal proportion, remained unchanged at some deeper and shorter stops.Conclusion Asymmetric kinetics can more closely simulate the gas movement in the body to effectively control the conservativeness of decompression,and adapt to different decompression requirements by adjusting the half-saturation time ratio.
