Abstract:

Smartwatches have become popular for blood pressure estimation, offering continuous monitoring with advanced convenience. However, clinical guidelines have not fully endorsed their use due to validation concerns. Many studies have compared watch-based BP measurements with cuff-based devices, but there is no clear consensus. To overcome previous methodological limitations, we collected systolic blood pressure measurements from both watch and cuff devices simultaneously, taking two readings at the same time of measurement (six participants over four days). Simply averaging the difference between watch and cuff measurements was slightly above the clinical threshold. Average error depended on individuals and calibration. Proper calibration may achieve clinically acceptable accuracy. The data showed that cuff BP measurements also vary, affecting comparative accuracy. After adjusting the inconsistency of cuff-based devices, watch-based blood pressure errors were within the clinical threshold. Daily variation analysis indicated watches being more conservative. The watch was able to distinguish participants with higher or lower daily standard deviations. The circadian cycle detected by the watch showed some relation to the cuff, but it is too early to confirm statistically significant similarity. This study evaluated the validity of watch-based BP monitoring from various perspectives, concluding that the watch might be valid for clinical use in young consumers for preventive or pre-diagnosis purpose. We also provided methodological guidelines for validating watch devices by cuff-based devices.
