This paper describes a method of measuring blood preasure based on pulse-transit-time. Transducer array based on electro-mechanical film material was employed to detect pulsations non-invasively on the radial artery, while its blood flow was blocked by an occluding cuff. Venous blood preasure was measured simultaneously from a vein on the same hand, and into-arterial blood preasure was obtained from the radial artery on the other hand by means of a catheter tip. Blood preasure was measured in 16 healthy young persons in supine and sitting position during increasing and decreasing cuff preasure. Correlation calculations were performed to assess the performance of the transducer array and the accuracy of the measurement.
