  • Method of continuous measurement of blood pressure in humans
    Patent number: 5237997
    Abstract: In a process for continuous measurement of blood pressure, the mean blood essure is derived from the measured pulse wave duration. The other blood pressure parameters are obtained by combination with an optoelectrical determination of blood volume density in a typical manner at the ear lobes. An initial individual basic calibration of the blood pressure values is carried out by a conventional method. In addition, a continuous automatic optoelectronic post-calibration is carried out. The measuring sensors are preferably a pair of ear clips and ECG electrodes or a photoelectric sensor. The method can be used to particular advantage in prevention and diagnosis.
