<p>An apparatus for non invasive estimation of intraarterial blood pressure comprising: first means (70,SA2,SB2) for obtaining the velocity of propagation of a pulse wave; second means (72,SA3,SB3,SA4,SB4) for obtaining at least one between the heart rate and an area defined by a volume pulse wave; third means (80,SB5) for estimating the blood pressure according to a predetermined mathematical relationship including a plurality of coefficients, fourth means (84,SC1 to SC4) for determining activity of the autonomic nerve system, based on at least one between fluctuations of blood pressure and fluctuations of the heart rate, and fifth means (90,SC5 to SC10) for changing, based on the activity of the autonomic nerve system, at least one of the coefficients of the expression, so that the expression including the changed coefficient amplifies a change of an estimated blood pressure from a prior estimated blood pressure. <IMAGE></p> |
