A New Method of Continuous Blood Pressure Measurement Based on the Pulse Image Sensor

Abstract:

In order to find a new measurement method for continuous blood pressure (BP), pulse image sensor, pressure sensor and data acquisition card MP425 were used to build the BP simulation platform of multi-information synchronous acquisition, including dynamic pulse images, pressure on the wrist (POW) and BP signals. Multi-point pulse wave (PW) amplitudes of film grid on the pulse image sensor were extracted from the dynamic pulse images by grid area method. Diastolic BP (DBP) and systolic BP (SBP) were estimated by multi-linear regression analysis. The results show that the maximum error of SBP (mmHg) and DBP (mmHg) satisfy the AAMI requirements (mmHg).
