FIELD: medicine; clinical physiology. ^ SUBSTANCE: measure frequencies of warm reductions (Ft), oxygen consumption (Qt), concentration of haemoglobin in blood (n), saturation of arterial blood by oxygen (ya). Count value of factors A and B under the formula: Ft=A+B*Qt and K value under the formula: K=64500/(22.4*4*(ya-0.12). According the obtained value, calculate size of a stroke output of blood (Vc) under the formula: (Vc)=K/(n*B). Size of minute volume of circulation (Jt) under the formula: Jt=Vc*Ft. Size of shunting stream in the big circle of circulation (M) under the formula: M=A*Vc. Size of saturation of the admixed venous blood oxygen (Yv(t)) under the formula: Yv(t)=ya-((ya-0.12)*B*Qt/(A+B*Qt)). ^ EFFECT: simplification of procedure of definition of parametres of circulation during exercise stress. ^ 2 tbl, 2 ex |
