| Popis: | Two methods of blood pressure measurement in fingers are presented. One method is based on blood pulse delay-time between proximal cuff and distal pulse sensor. On the time-delay curve the first minimum which occurs during deflation determinate the diastolic pressure. The another method is based on pulse amplitude differences which occur between proximal cuff signals and distal pulse sensor signals during deflation time of proximal cuff. The amplitude difference is lowest after diastolic pressure. The pressure in the cuff corresponding to the 45% of the difference between highest and lowest amplitude difference taken from lowest value is considered to be diastolic pressure by this method. This two methods and their combination are proved to be quite accurate. The accuracy of this measurements is given as well. Blood pressure measurement on the fingers is more comfortable for blood pressure measurement than on the upper arm. |
