Belaventseva A.V., Kulchin Yu.N., Romashko R.V., Zaporozhets T.S., Persiyanova E.V., Lyakhova L.P., Kamshilin A.A. Diagnostics of physiological processes in living tissues by the method of optical visualization of blood pulsation //Journal of Instrument Engineering. - 2019. - Vol. 62, No.3, P.
The possibility of using the method of blood pulsations visualization for studying a process of human living tissues thermal relaxation was investigated. It is experimentally shown that a blood pulsation amplitude (BPA) in a tissue depends on the thermal effect on it. It has been established that a tissue cooling process leads to BPA decrease, and a tissue heating process is accompanied by a BPA increase. An increase of BPA rate is an individual subject's characteristic, which can serve as a parameter of blood vessels vasomotor reactivity on the temperature changes.
