ABSTRACT:
Intra-arterial blood pressure is noninvasively measured and monitored by an electromechanical force sensor which is made up of an array of individual pressure or force sensing elements, each of which has at least one dimension smaller than the lumen of the underlying artery wherein blood pressure is to be measured, and the individual pressure sensitive element used to monitor blood pressure is within one artery's diameter of the pressure sensitive element that generates the waveform of maximum pulse amplitude and generates a waveform having a spatially local minimum of at least one of the diastolic and systolic pressures.
