Research objective is to study substantiation of noninvasive method of blood viscosity and hematocrit monitoring. it contains the results of theoretical, experimental and clinical studies held to examine the mechanism of pulse wave distribution. The interrelation between pulse wave parameters, pulse wave velocity, systolic and diastolic blood pressure, blood viscosity and hematocrit has been revealed. Noninvasive method of blood viscosity and hematocrit determination has been worked out. it is distinguished by the following factors: pulse wave of the main artery registered at two limb levels, the amplitude of pulse wave, the duration of its trailing edge and the time of pulse wave distribution. Systolic and diastolic blood pressure are recorded. Blood viscosity and hematocrit calculations are made by means of mathematical treatment with the help of original program. the device for noninvasive blood viscosity and hematocrit monitoring has been created on the basis of elaborated method. Data precision obtained by noninvasive measurement of hematocrit and blood viscosity does not exceed 3%.
the clinical use of noninvasive method enables to approach the problem of atherosclerosis prevention, to improve the results of atherosclerosis treatment and to look at it from critically new noninvasive positions
