Abstract:
1. A non-invasive blood pressure monitoring system comprising: a pressure cuff configured to surround a limb of a patient and having an adjustable circumference; a single continuous strip of resistive material attached to the pressure cuff and positioned to extend lengthwise in a circumferential direction about the limb of the patient when the pressure cuff is positioned on the patient, the strip of resistive material extending between a first end and a second end; a conductive portion attached to the pressure cuff and positioned to engage the strip of resistive material when the pressure cuff is applied to the limb of the patient; and a controller operatively connected to the strip of resistive material and the conductive portion of the pressure cuff, wherein the controller is adapted to estimate the circumference of the pressure cuff based upon the position of the conductive portion along the length of the strip of resistive material between the first and second ends.
