Published Date: Aug 5, 2025

Abstract

BACKGROUND: Photoplethysmography has been used to assess vital signs since the late 19th century. Recently, camera-based photoplethysmography systems have gained attention due to their noninvasive nature. However, challenges such as low perfusion, motion artifacts, and ambient light interference limit their use during surgical anesthesia. This study evaluated the efficacy of a camera-based system (FaCare) compared with that of a conventional contact monitor (GE HealthCare CARESCAPE B850 patient monitor) in measuring heartbeat intervals during various stages of surgical anesthesia.
