Contactless and device-based recording of cardiovascular vital signs
Cardiovascular Physiological Signal Recording Project
Chinese University of Hong Kong · NCT07035795
This project will test whether camera-based (remote PPG) and conventional device PPG can record heart rate, oxygen level, breathing rate and related signals in adults with known medical conditions.

What this trial studies
This is an observational project that collects conventional physiological signals (blood pressure, pulse rate, respiratory rate, SaO2, and cardiac rhythm) alongside PPG from standard monitors and, with consent, video-based remote PPG (rPPG). Demographic and clinical data (age, sex, medical history, medications, height, weight) will be recorded to support model training and validation. Machine learning methods will be used to correlate device PPG and rPPG signals with clinical measurements and explore the ability to derive parameters such as blood pressure. Participants' electronic health records may be accessed for up to five years to study associations with long-term outcomes.
Who should consider this trial
Good fit: Adults over 18 with a known medical disease who can comply with physiological recordings and provide informed consent are ideal candidates.
Not a fit: People who cannot give informed consent, cannot sit still for recordings, or decline video recording are unlikely to benefit from the rPPG components of the project.
Why it matters
Potential benefit: If successful, this approach could enable less obtrusive, potentially contactless monitoring that reduces wires and cuffs and improves comfort and compliance for patients.
How similar studies have performed: Prior work has shown rPPG can reliably capture heart rate and oxygenation signals, but accurate contactless blood pressure estimation remains preliminary and under active research.
