More Information
Summary:The invention relates to a method and a measuring device for continuously non-invasively determining at least one cardiovascular parameter, preferably the arterial blood pressure, at an extremity containing an artery, the measuring device comprising a receiving element that can be attached to the extremity and is suited to at least partly surround the extremity, and comprising a flexible bubble which is supported on the receiving element, acts on the extremity and is filled with a fluid. According to the invention, an actuator which is suited to vary the pressure in the flexible bubble is placed in or on the receiving element, and the flexible bubble includes a pressure sensor which is in contact with the fluid in the flexible bubble and which is suited to continuously measure the absolute pressure value. The measuring device further comprises a unit suited to measure the pulsations generated by the volume flow in the artery, and a control unit having two different modes of operation, i.e. a measuring phase and an interpolation phase.
