Contact pressure standardization is required for reliable PPG BP estimates; leaves open optimal calibration methods for clinical validation.
Should PPG sensor contact pressure be taken into account for cuff-less blood pressure measurement?
Contact pressure is a critical variable that must be accounted for in the calibration of cuff-less PPG-based blood pressure measurement devices.
Chandrasekhar et al. (2020) studied this question.
