This article addresses the issues of capturing and processing of pulse waves. Presents devices developed in IMASH RAS, as well as their foreign counterparts. Describes the method of determination of aortic systolic blood pressure. The results of the validation of the instrument cardiopulmonar «Pulse», compared to the same device from an Australian company «Sphygmocor». In the basis of domestic equipment is a sensor with a fiber-optic measuring transducer-probe. The use of fiber optics for the primary Converter of information allowed to solve the questions of the parametric reliability of the sensor and galvanic isolation between the measurement object and the instrument. In addition, managed to create the form factor of the sensor, suitable for mounting on the hand under the harness. This distinguishes the device IMASH RAS, because it frees the doctor\'s hands for simultaneous examination of a patient, e.g., using other sensors in the area of the carotid artery. In the group of 30 surveyed is shown that the proposed device provides sufficient precision and reproducibility in the determination of the key parameter of Central heart rate – systolic blood pressure.
