Arterial line (AL) transducers are commonly used to measure continuous blood pressure (BP) in intensive care units, but they can cause clinical complications. In this study, we aimed to evaluate the accuracy and feasibility of wireless, non-invasive photoplethysmography (PPG)-based devices for continuous BP measurement.
Specifically, we compared two PPG-based device configurations - wristwatch and chest-patch monitors - with the standard AL method. The study's findings could have important implications for the use of non-invasive methods for continuous BP monitoring in clinical settings, potentially reducing the risk of complications associated with invasive techniques.
