NHS, Oxford University in U.K. pilot study of camera-based patient monitoring

Innovate UK is funding a trial for a camera-based vital sign technology from startup Oxehealth.

The startup spun out the University of Oxford's Institute of Biomedical Engineering in 2012 and the study is being conducted in collaboration with it. In the study, Oxehealth will monitor simultaneously 5 essential patient monitoring vital signs: heart rate, breathing rate, blood oxygenation, blood pressure and temperature. The technology is based on images from a video camera in the patient's room.

The resulting video is analyzed continuously via a set of algorithms to detect significant variations in those 5 vital signs. It works at night via invisible infra-red illumination, which allows the patient to sleep undisturbed. Upon any significant changes, hospital staff are alerted with an alarm.

The study will be conducted in an upper gastrointestinal ward of patients who have had cancer surgery. It will focus on the two to five days after surgery, when accurate monitoring is essential.
