Abstract
An arterial pressure control system comprises an inflatable cuff for encircling the artery and a fluid pump connected to inflate the cuff. The outlet pressure of the pump is controlled by a programmable controller which receives a feedback signal from a pressure sensor contacting the artery downsteam from the cuff. The output of the pressure sensor is compared with a reference value so that the feedback signal to the controller represents the difference between the actual arterial pressure and the desired pressure. The controller thereupon regulates the output pressure of the pump so as to inflate or deflate the cuff as needed to maintain the desired arterial pressure.
