Abstract

We present an image-free ultrasound technology – ARTSENS® Duo, for calibration-free cuffless measurement of central blood pressure (BP). This technology performs a local assessment of incremental pulse wave velocity (PWV) and arterial wall dynamics in a simultaneous fashion, for direct evaluation of BP without any calibration. Methodological considerations concerning this technique were identified and addressed for achieving reliable measurements of BP parameters and waveform from the carotid artery. The performance evaluated on a cohort of 10 subjects (age = 26 ± 3) demonstrated the measurement reliability, with a RMSE < 7.4 mmHg and beat-to-beat variation < 6.3 %.
