Abstract
An adaptive processing of the pulsatility signal can improve the pulse wave analysis (PWA) leading to a better blood pressure estimation. The technique is based on transforming the pulsatility signal so that the fiducial points required for the PWA are well-defined.
Claims12
A method for translating pulsatility signals, comprising:
- receiving input pulsatility signals from a photoplethysmography sensor;
- applying a signal transformation to the pulsatility signals to produce target pulsatility signals;
- and
- generating blood pressure values from the target pulsatility signals by referencing fiducials in the target pulsatility signals.
