What this trial studies

This study aims to gather data to assess the effectiveness of a mobile application called OptiBP, which utilizes advanced machine learning techniques to estimate blood pressure. Participants will take blood pressure readings using a traditional cuff-based monitor while simultaneously capturing an optical signal with their smartphone camera. The goal is to evaluate the accuracy and reliability of this innovative approach in estimating blood pressure in a general population setting.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who reside in the United States and have access to both an Android smartphone and a cuff-based blood pressure monitor.

Not a fit: Patients with known skin sensitivities to nickel/chromium or those with hand lesions that prevent proper smartphone camera use may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a convenient and accurate method for individuals to monitor their blood pressure using their smartphones.

How similar studies have performed: While the use of mobile applications for health monitoring is growing, this specific approach utilizing machine learning for blood pressure estimation is relatively novel and has not been extensively tested in prior studies.
