Blood Pressure Measurement Based on the Camera and Inertial Measurement Unit of a Smartphone

2022-07-19

Abstract excerpt

<h4>Background: </h4> This study assessed the accuracy of AlwaysBP (test) in blood pressure (BP) measurement compared with the standard cuff-based manual method of brachial BP measurement (reference). AlwaysBP is a smartphone software that estimates systolic BP (SBP) and diastolic BP (DBP) based on the pulse transit time (PTT). The PTT was calculated from the finger photoplethysmogram using the camera and from sei...
