Contactless measurement of vital signs in the emergency department
Contactless Assessment of Patient Vital Signs for Triage Using Remote Photoplethysmography in the Emergency Department - 1 Observational Study (CAPTURE-1 Study)
This study is testing a new camera-based method to see if it can accurately measure vital signs like heart rate and blood pressure in adults coming to the emergency department without needing to touch them.

What this trial studies
This observational study evaluates the accuracy of a camera-based method called remote photoplethysmography (rPPG) for measuring vital signs without physical contact. By analyzing facial video data, the study aims to estimate vital signs such as blood pressure, heart rate, respiratory rate, and oxygen saturation in adult patients presenting to the emergency department. The study will recruit participants over a two-month period, collecting data to assess the effectiveness of this innovative technology in a clinical setting.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 years and older who can provide valid written consent.
Not a fit: Patients under 18 years old or those unable to provide consent due to mental illness will not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could enhance triage efficiency and patient monitoring in emergency settings.
How similar studies have performed: While the use of remote photoplethysmography is a novel approach, similar technologies have shown promise in other settings, indicating potential for success.
