Functional diagnostics of the lungs is usually based on the state of correlation of gas exchange in the alveolar-capillary system of the lungs. It is known that respiration is one of the powerful factors involved in maintaining a certain acid-base balance. In humans, with normal lung and cardiovascular function, blood pH is 7.35-7.45, arterial oxygen saturation is 96-98%, oxygen capacity is 18-24 vol.%, Plasma carbon dioxide voltage is pCO2 35 -45 mm Hg. Art., CO2 content - 45-50 vol.%; hematocrit - 40-54% (Zunderman and Berner).
