Abstract
A method for the continuous non-invasive measurement of blood pressure includes at least one first pressure cuff and one second pressure cuff of comparable or identical size, each cuff including an inflatable pressure measuring chamber applicable to a first and a second body part or region containing an artery. The first pressure cuff has a first plethysmographic sensor connected to a regulating and control device used to regulate the pressure in a first pressure measuring chamber by means of a measuring signal of the plethysmographic sensor. The first pressure measuring chamber is connected to a pressure sensor in order to obtain a pressure measuring signal. The second pressure measuring chamber is a reference pressure chamber that can be regulated at the same time as the first pressure measuring chamber, independently therefrom, and can be regulated by the regulating and control device according to a pre-determinable pressure function.
