ABSTRACT:
A method of measuring blood pressure where a plurality of oscillometric data values are measured from a subject at a plurality pressure levels, a function curve having the shape of an oscillometric envelope is selected and computational model fit to the data, using the Gauss-Marquardt method of model fitting. Once the curve is model fit, blood pressure is measured using the oscillometric method. Included in the step of model fitting is the step of computing the parameter of the function curve that minimizes the error between the function curve and the data values at the respective pressure levels thereby approximating the oscillometric envelope based upon data values.
