Non-invasive cuff-free methods of blood pressure measurement are being developed actively that will make measuring in everyday life conditions comfortable. The method offered includes 4 steps: choice of a finger, calculation of a generalized skin option, presetting and measuring. To improve the accuracy of measurements, the finger with the greatest temperature sensitivity was revealed and the value of generalized skin option was defined during the experimental verification. In accordance with the developed algorithm the presetting step is meant to determine the coefficient of proportionality which is necessary for measuring blood pressure. This method enables the increase of accuracy of measurements due to taking into account the adaptation to changes in the ambient temperature and individual skin options.
