Influence of Sex, BMI, and Skin Color on the Accuracy of Non-Invasive Cuffless Photoplethysmography
Vital signs obtained by photoplethysmography-based devices might be influenced by subcutaneous fat and skin color. This observational comparison study aimed to test the accuracy of blood pressure (BP) measurements between a photoplethysmography-based device and cuff-based BP device in ambulatory individuals, coming for a routine BP checkup.
In this study, we found a high level of accuracy of BP obtained by cuffless PPG-based BP device as compared to cuff-based BP measurements, an agreement that was not influenced by sex, BMI, or skin color.
