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

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
