[A photoplethysmo-tonomanometer for examination of the vascular system and measuring hemodynamic parameters]

A new method and an apparatus for noninvasive medical investigations of the vascular system are considered. During the investigations, the two known methods of arterial pressure measuring, namely Korotkov's method and Penaz's method were used. The combination of the methods and a special procedure algorithm allow the measuring, in addition to arterial pressure, of the other important hemodynamic parameters such as venous pressure, the characteristic time parameters of blood redistribution between arterial and venous vessels and pulse wave velocity. The diagram of the photoplethysmo-tonomanometer and the measuring algorithm procedure are provided.
