METHOD FOR DETERMINING REST HYPO-NORMO-HYPERVOLEMIA OF INDIVIDUAL'S BLOOD FLOW Russian patent published in 2014 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: hypo-normo-hypervolemia of the blood flow is assessed by deriving the total blood volume (TBV) deviation from a required total blood volume (RTBV) (D_tbv, in %) by formula. And if D_tbv±10%, normovolemia is then stated; if D_tbv>+10%, hypervolemia is diagnosed; D_tbv<-10% shows hypovolemia. Thereafter, hypo-normo-hypervolemic deviations are related to body weight anomalies (A_bw) by formula. The hypervolemic variations with D_tbv+A_bw>0 are related to overweight. If D_tbv+A_bw<0 - to changes of the blood flow state specific for hypertension. The hypervolemic variations with D_tbv+A_bw<0 are connected to relative bodyweight reduction. If D_tbv+A_bw>0 - to an increase in the body reserves. The rest TBV is determined by formula that is ensured by deriving the minute blood volume index (MBVI), which is specified by tetrapolar rheocardiography or ultrasound examination of the heart by formula.

EFFECT: method enables more reliable factors reflecting the functional state of the cardiovascular system by taking into account physically and physiologically ground factors in calculations.
