Abstract

The system measures circulatory parameters external by using a band which can compress part of patient's body to varying degrees. This transforms a shock wave resulting from intra-arterial phenomena into an electrical value. Transformation is effected by an electronic differential pressure gauge. The electrical value can be a potential difference delivered continuously, and proportional to the normal intra-arterial phenomena or those engendered by the back pressure in the band.
