[Pneumocalorimetric assessment of functional state of the cardiorespiratory system in polyclinical practice].

Physical efficiency (PhE), maximal calorific capacity (MCC) and Pneumocalorimetric index which conditions the function of the respiratory apparatus can be described by the following equation: PhE = 59.9 . MCC + 33. An error of PhE calculated with the above mentioned technique doesn't exceed 12,5%. The use of pneumocalorimetric enables to assess the functional state of the cardiorespiratory system by determining PhE, labour-intensiveness of the method is 5.1 minutes per a test.
