Key result
Acceleration plethysmogram wearables feasibly track carotid pulse pressure and systolic BP with high reliability.
Why the study?
Is an acceleration plethysmogram (APG) based wearable pressure-sensing system feasible for tracking changes in carotid pulse pressure and systolic blood pressure?
Is an acceleration plethysmogram (APG) based wearable pressure-sensing system feasible for tracking changes in carotid pulse pressure and systolic blood pressure?
An APG-based wearable pressure-sensing system demonstrates feasibility, reliability, and repeatability for tracking changes in carotid pulse pressure and systolic blood pressure.
Supports wearable carotid monitoring development; leaves open prospective validation before clinical use.
) were 78 % and 89 % as compared to 33 % and 19 % in carotid PP and systolic blood pressure (SBP), respectively. Reliability (SNR > 38 dB) and repeatability (CoV < 10%) were seen in the obtained transcutaneous pressure signals. The study limitation is identifying an appropriate calibration or model for carotid BP estimation. This study reveals the feasibility of using an acceleration plethysmogram (APG) based wearable pressure-sensing system for tracking changes in carotid PP and SBP which could pave the way for wearable systems for ambulatory assessment of central BP for clinical and home use.

Girish et al. (2024) studied Carotid pulse pressure monitoring. Acceleration plethysmogram (APG) based wearable pressure-sensing system was evaluated on Carotid pulse pressure and systolic blood pressure tracking. An acceleration plethysmogram-based wearable system demonstrated feasibility for tracking carotid pulse pressure and systolic blood pressure, showing reliability (SNR > 38 dB) and repeatability (CoV < 10%).
