[A quantitative assessment of the blood supply to the head by indirect rheography]

Clinical-experimental basis of the possibility of application of the method of indirect rheography of head (IRH) in wide clinical practice was presented. Estimation of the results reproduction and accuracy of the method was performed too. 40 healthy individuals of both sexes at the age of 18-50 and 102 patients with spinal osteochondrosis, arterial hypertension and neurocirculatory dystonia were examined. It was determined that IRH provided 93% of results reproduction and its precision was 90% and higher in comparison with ultrasound method. It was established that head circulation was 750-1200 ml/min or 12-24% of cardiac output in healthy individuals. The results of the study of head blood circulation in some groups of patients were also discussed.
