Influence of Sex, BMI, and Skin Color on the Accuracy of Non-Invasive Cuffless Photoplethysmography

Updated: Jun 12, 2023

The objective of this observational comparison study was to assess the accuracy of blood pressure (BP) measurements obtained from photoplethysmography-based devices in ambulatory individuals who had routine BP checkups. Subcutaneous fat and skin color are regarded as potential factors that could affect the precision of these measurements.

The study conducted a comparison of the readings obtained from a cuff-based BP device and a photoplethysmography-based device to determine their level of agreement. The results of the study showed that the BP measurements obtained from the cuffless PPG-based device were highly accurate and consistent with those obtained from the cuff-based device, regardless of the individual's sex, BMI, or skin color.
