What this Trial Is About
Researchers are evaluating a non-contact, camera-based physiological monitoring technology using remote Photoplethysmography (rPPG) in a perioperative setting, including anesthesia induction, surgery, and recovery. This study aims to assess the feasibility and accuracy of this technology in measuring vital signs such as heart rate, blood pressure, and blood oxygen levels compared to standard contact-based clinical monitors. The research focuses on patients undergoing surgery, where traditional monitoring tools may cause skin injury or pose infection risks. The study uses investigational non-contact rPPG software installed on devices like the Logitech C930 camera, iPhone 16 Pro Max, and Samsung Galaxy S24 Ultra to capture facial video and estimate vital signs. These results are compared simultaneously with clinical gold-standard monitors including Masimo Root, SedLine O3, and Radical-7 systems during different surgical phases. The monitoring covers the entire perioperative period, from anesthesia induction to recovery, lasting approximately 2 to 6 hours. Participants will be monitored concurrently with both systems without interrupting routine care. Researchers will collect synchronized data to analyze the accuracy and success rates of the non-contact system in measuring heart rate, blood pressure, and oxygen saturation. Assessments include mean absolute error across hardware platforms during surgery. The study is designed to optimize algorithms and explore this technology’s potential as a supplementary or alternative monitoring solution in operating rooms.
