Is this trial a fit for you?
✓Likely a good fit
Adults over 18 scheduled for surgery under general anesthesia at Taipei Veterans General Hospital with ASA physical status I–III and a face that can be imaged are ideal candidates.
✕Probably not a fit
Patients who are under 18, pregnant, have facial coverings or severe facial trauma or edema that prevent imaging, or cannot consent are unlikely to benefit from this approach.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This feasibility study tests a remote photoplethysmography (rPPG) software that analyzes facial video from standard cameras to estimate heart rate, blood pressure, and SpO2 during the perioperative period. Video will be captured using standard devices (Logitech C930, iPhone 16 Pro Max, Samsung Galaxy S24 Ultra) while patients undergo routine monitoring with clinical gold-standard devices (Masimo Root, SedLine O3, Radical-7) for simultaneous comparison. Data will be collected across pre-operative, intra-operative, and post-operative phases in adults under general anesthesia (ASA I–III) to assess consistency and algorithm robustness in dynamic OR conditions. Results will inform algorithm optimization and the feasibility of using camera-based monitoring as a supplementary option when contact sensors are unsuitable.
Why it matters
Potential benefit: If successful, this technology could provide continuous vital signs without skin contact, reducing skin injury and cross-infection risks and improving monitoring for patients who cannot tolerate contact sensors.
How similar studies have gone: Previous clinical validations of rPPG have shown promising results in controlled settings, but its performance in the dynamic environment of the operating room remains less well established.
