ABSTRACT:
A method of determining the instantaneous arterial blood pressure of a subject which is a living being without utilizing entry of a needle or the like along an artery is capable of a high degree of accuracy and comprises the steps of applying a pressurizable device in the region of an artery and controllably pressurizing that device with fluid to an extent sufficient to eliminate arterial wall movement without collapse of the artery, the fluid pressure in the pressurizable device being monitored and providing a measure of the instantaneous arterial blood pressure of the subject. A preferred form of pressurizable device is an annular ring or cuff comprising a rigid body of annular shape over the inner surface of which is stretched a latex membrane which is pressurizable with distilled water.
