Abstract

Based on the respiratory and circulatory system, a dynamic model describing oxygen metabolism in human body was set up. The effect on oxygen pressure in the tissue due to the change of the parameters was revealed through numerical analysis to the parametric equation of the model. Two treating methods to raise oxygen pressure in the tissue were worked out, which accorded with the results of clinical observations. The results of such model showed that the abnormality of the circulatory and respiratory parameters always lead to a reduction of PO2 (O2 pressure) in tissue fluid, and then a Lung Qi-Deficiency Syndrome (QDS). This article also discuss the quantitative relationship between the changes of the parameters of the heart-lung system and the oxygen pressure in the tissue, then provide index to evaluate clinical treatment and analyze the body's oxygen metabolism, which is great significant for the precaution and treatment of low oxygen environment.
组织供氧模拟及其与肺气虚的关系
以呼吸循环系统为基础,建立了描述人体氧代谢的动态模型。通过对模型参数方程的数值分析,揭示了参数变化对组织内氧压的影响。提出了两种提高组织内氧压的治疗方法,与临床观察结果一致。该模型结果表明,循环和呼吸参数异常总是导致组织液PO2 (O2压)降低,从而导致肺气虚证(QDS)。本文还探讨了心肺系统参数变化与组织内氧压的定量关系,为临床治疗评价和机体氧代谢分析提供指标,对低氧环境的防治具有重要意义。
