[The circulatory and respiratory dynamic mechanisms of lung Qi-deficiency].
As the transportation of O2 and CO2 inside human body is an integrated aspect of Qi-blood transportation, a hemodynamic model is established based on the analysis of the respiratory and circulation system. The results of such model show 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 model can be used to quantitatively explain, to some extent, the physiological phenomena of Lung QDS, and could combine all the discoveries of in clinical researches, on Lung QDS. The measurement of Po2 in tissue fluid as an index to analyze Lung QDS is in accordance with TCM and TMM (the theory of modern medicine). This model may provide a new approach in clinical research of Lung QDS.
