[Topics of clinical physiological tests--pulmonary function--proposal of physio-chemical tests].

: Pulmonary functions are classified as respiratory and non-respiratory. Although the mechanisms of non-respiratory pulmonary function have already been established, no new tests of respiratory pulmonary function have been developed for a long time. Thus, we report here a new analytic test of respiratory pulmonary functions. The new analytic method is physio-chemical analysis, in which the chemical factors of lungs are estimated from the physiological characteristics of lung during respiration. As examples, this report shows the method of exchanging mechanical energy to chemical energy in a comparison of lung ventilatory work between smokers and non-smokers. This report discusses the relationship between chemical energy and ATP in the blood of pneumoconiosis patients.
