ClinConnect Summary

This clinical trial is studying a new, contactless way to measure vital signs (like heart rate and blood pressure) using a technology called remote photoplethysmography (rPPG). This method uses a camera, such as those on smartphones, to analyze subtle changes in skin color that occur when blood flows beneath the skin. By doing this, the researchers hope to see if this technology can accurately estimate vital signs without needing to touch the patient. The study will involve adult patients who come to the Accident and Emergency Department at Queen Mary Hospital between August and October 2024.

To participate, you must be at least 18 years old and able to give written consent. If you are a stable patient categorized as semi-urgent or non-urgent, you may be eligible. During the study, participants will sit still while both the contactless method and a standard manual method are used to measure vital signs at the same time. The researchers will also ask how comfortable participants feel with each method. This study aims to see how well the contactless technology works compared to traditional methods and to understand patients’ experiences with these different ways of measuring vital signs.
