где Δr - прирост радиуса мелких артерий и артериол;
АДср= ДАД+(САД-ДАД): 3;
Ркап. исх - среднее капиллярное давление исходное;
Qисх - объемный кровоток исходный;
Ркап. г - среднее капиллярное давление на фоне реактивной гиперемии;
Qг - объемный кровоток на фоне реактивной гиперемии,
и при значении Δr от 1,43 до 1,91 для предплечья, и от 1,50 до 2,04 для голени, определяют нормальную величину прироста радиуса.A method for determining the increase in the radius of peripheral arteries against the background of reactive hyperemia by measuring volumetric blood flow in the region of the forearm and / or lower leg using occlusive plethysmography, characterized in that blood pressure is determined by the Korotkov method and average blood pressure is calculated, and the average capillary pressure is additionally determined from the plethysmogram curve in the initial state and against the background of reactive hyperemia and calculate the increase in the radius of small arteries and arterioles with respect to the initial rad formula usu
where Δr is the increase in the radius of small arteries and arterioles;
ADSr = DBP + (SAD-DBP): 3;
Rkap. ref - initial capillary pressure;
Qix - volumetric blood flow source;
Rkap. g - average capillary pressure against a background of reactive hyperemia;
Qg - volumetric blood flow on the background of reactive hyperemia,
and when the Δr value is from 1.43 to 1.91 for the forearm, and from 1.50 to 2.04 for the lower leg, the normal value of the radius increment is determined.
