METHOD FOR ASSESSING PULMONARY BLOOD FLOW Russian patent published in 2015 - IPC A61B5/02 A61B5/26 A61B5/145 G01N33/48 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, namely to pulmonology, cardiology, gerontology and sports medicine, and can be used for assessing the pulmonary blood flow by assessing the capillary pulmonary blood flow and intrapulmonary venoarterial bypass. That is ensured by measuring heart rate a minute, haemoglobin concentration (Hb g/l), total oxygen consumption (CO_2(TOTAL) ml/min), arterial oxygen saturation (S_ART % or decimal portions 1) and mixed venous saturation in the greater circulation (GC) (Sv% or decimal portions 1). MBV (l/min) is calculated according to the measurements of Hb, CO₂, S_ART, S_V. Certain formulas are used to calculate the capillary pulmonary blood flow and intrapulmonary venoarterial bypass.

EFFECT: presented versions of the method enable the precise determination of ventilation-perfusion relations in lungs, as well as elimination of direct instrumental methods for measuring the capillary pulmonary blood flow.
