METHOD FOR MEASURING PRESSURE IN PULMONARY CAPILLARIES Russian patent published in 1997 - IPC

FIELD: medicine; cardiology; pulmonology; sports medicine; medicine for polar expeditions and alpinists. SUBSTANCE: novelty of method resides in fact that lung capillary pressure is measured within two ranges, of which 1st range extends from zero wave of electrocardiogram (O ECG) up to 1st heart sound of phonocardiogram, and 2nd range extends from IInd heart sound of phonocardiogram up to maximum opening of mitral valve. Following formula is used to calculate capillary pressure: O ECG - 1st sound PCG (s) x 36.6 PCP = ---------------------------------------------- - 2 mm Hg, IInd sound PCG - max. opening of mitral valve wherein PCP is pressure in pulmonary capillaries, mm Hg; O EKG is zero wave of electrocardiogram; Ist sound of PCG is 1st heart sound of phonocardiogram; IInd sound of PCG is 2nd heart sound of phonocardiogram. EFFECT: simplified pressure measurement procedure; shorter time for pressure measurements.
