Abstract

A criterion of permissible integral supercritical gas oversaturation of the body tissues was established using mathematical modelling. The heart of this criterion is that if integral supercritical oversaturation of tissues by gases does not go beyond a permissible level, gas bubbles do not reach critical volumes and give rise to decompression sickness symptoms. An equation was also built to calculate integral supercritical oversaturation of tissues during and after decompression. Permissible integral supercritical saturation values were determined for animals from mice to dogs and humans basing on literary threshold pressures with saturation and follow-on one-step decompression.

摘要

通过数学建模建立了人体组织允许的整体超临界气体过饱和度标准。该标准的核心是,如果气体对组织的整体超临界过饱和度不超过允许水平,气泡就不会达到临界体积,也不会引发减压病症状。还建立了一个方程来计算减压过程中和减压后的组织整体超临界过饱和度。根据文献中关于饱和及后续一步减压的阈值压力,确定了从小鼠到狗再到人类等动物的允许整体超临界饱和度值。
