Millimeter wave radar will be used to conduct non-contact monitoring continuously for patients' vital signs (eg. respiratory rate, heart rate, and chest/abdominal movement). The monitoring information will be transmitted to the central system through network and displayed in real time. Comparison with polysomnography will be done to examine the consistency between the two devices in diagnosing sleep breathing disorders. The predictive model of acute exacerbations of COPD will be established with the baseline indicators considered.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
