Abstract
A method and apparatus for the non-invasive examination of the blood circulation of a living organism uses a device having: a pair of sensors (18, 19), each of which detects the value .beta. (t) of a measurement value that changes during one pulse wave with the blood pressure of the organism and thereby with time, and transmits this value through signals; a pair of pressure sleeves for connecting the sensors with tissue of the organism through which arterial blood flows; and an electrical unit (21) for evaluating the signals of the mentioned sensors. The method includes setting two subdiastolic pressures which differ from each other by a small value in the two sleeves, transmitting signals obtained from the two sensors (18, 19) to the evaluating unit (21), and determining a circulatory function of the organism from transmitted signals in the evaluating unit.
