Abstract
A method for determining a physiological parameter, including: providing a PPG sensor device configured to measure a PPG signal; measuring a PPG signal on the user, the PPG signal containing at least two cardiac cycles; identifying PPG pulses from the PPG signal, each corresponding to a cardiac cycle and having a non-modulated component and a time-modulated component; for each PPG pulse, determining at least one venous-related feature indicative of the contribution of venous pulsatility to the time-modulated component of the PPG pulse; assigning a weighting factor to each pulse including calculating the weighting factor by using a weighting function including a mathematical operator inputted with the set of at least one venous-related feature; computing a weighted-average PPG pulse by using the PPG pulses and their respective weighting factors; and determining the physiological parameter by using the weighted-average PPG pulse.
