FIELD: medicine. SUBSTANCE: pressure of patient is monitored in intensive therapy ward by means of measurement of speed of propagation of pulse wave in two vessels simultaneously: in aorta and in artery. The method is based upon peculiarities of propagation of pulse wave along the elastic and muscular types of vessels (aorta and artery correspondingly). During process of monitoring of pressure, the value of relation of pulse wave propagation speed in aorta and in artery depending on average arterial pressure is used. EFFECT: improved truth of prediction of imminent condition of patient. 2 dwg
