Using a camera to measure blood pressure remotely
Development of Predictive Remote Photoplethysmography Algorithm for Blood Pressure Assessment and Monitoring
This study is testing whether a smartphone camera can accurately measure blood pressure by looking at changes in skin color, to see if it can help people monitor their blood pressure easily and without touching.

What this trial studies
This study explores the feasibility of using remote photoplethysmography (rPPG) technology to measure blood pressure through a smartphone camera. By analyzing subtle changes in skin color associated with blood flow, the study aims to develop a predictive model using artificial neural networks to estimate blood pressure accurately. The research will involve collecting rPPG waveforms and correlating them with blood pressure readings to validate the effectiveness of this contactless monitoring method. The ultimate goal is to create a mobile application that can provide users with reliable blood pressure assessments.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 21 and older who can provide informed consent and are not undergoing head or neck surgeries.
Not a fit: Patients under 21 years old or those requiring head and neck surgeries may not benefit from this study.
Why it matters
Potential benefit: If successful, this technology could offer a non-invasive, convenient method for individuals to monitor their blood pressure at home.
How similar studies have performed: While the use of rPPG for other vital sign measurements has shown promise, the application for blood pressure assessment is still novel and untested.
