Summary
Brief summary (as posted)
This study aims to evaluate the feasibility and accuracy of a non-contact, camera-based physiological monitoring technology in a perioperative setting (including anesthesia induction, surgery, and recovery).Conventional vital sign monitoring tools-such as ECG leads, blood pressure cuffs, and pulse oximeters-require direct skin contact, which may pose risks of cross-infection or skin injury in vulnerable populations (e.g., newborns or elderly patients). This research utilizes remote Photoplethysmography (rPPG) technology to estimate vital signs, including heart rate, blood pressure, and blood oxygen saturation (SpO2), by analyzing facial video captured via standard camera devices (Logitech C930, iPhone 16 Pro Max, and Samsung Galaxy S24 Ultra).The primary goal is to assess the consistency and stability of this non-contact system compared to clinical gold-standard monitors (Masimo Root, SedLine O3, and Radical-7) during actual surgical procedures. The findings will serve as a foundation for developing non-invasive, supplementary monitoring tools in dynamic clinical environments.

- label
- Perioperative Monitoring Group
- description
- Surgical patients who will be monitored simultaneously using both the investigational non-contact rPPG software (installed on laptop and mobile devices) and standard clinical monitoring systems (Masimo Root, SedLine O3, and Radical-7) across different surgical phases.
- interventionNames
- Device: Non-contact rPPG software
Primary outcomes (4)
- measure
- Accuracy of Heart Rate (HR) monitoring
- timeFrame
- From anesthesia induction to recovery (approximately 2-6 hours).
