  • Method for determining the arterial blood pressure in a non-invasive manner
    Patent number: 5099852
    Abstract: This method for establishing blood pressure in an artery employs the measurement results from two non-invasive sensors (5, 6) of artery diameter at two closely spaced locations (3, 4) separated by a distance .DELTA.x. The method provides for measuring the time spread .DELTA.t(7) between each pair of diameter measurements and establishing the propagation velocity of the pressure wave (9). Next, this value is compared with an expression (11) of the form c(D)= c(D, .alpha., .beta., .gamma., . . . ) which takes into account the physical behavior of the artery. This comparison permits one, following adjustment (12) based on a mathematical procedure for minimizing spreads, to calculate the parameters .alpha., .beta., .gamma., . . . of the relation given hereinabove. By replacing the parameters .alpha., .beta., .gamma., . . . by their values in a relation (10) D(p)= D(p, .alpha., .beta., .gamma., . . .
