Study Summary

The purpose of this study is to determine whether vital signs can be extracted from video. A secondary purpose is to create a database, including raw video, of "ground truth" physiological data on human subjects in order to test current and/or future approaches developed to extract vital signs from video. This research may have an immediate impact on not only the assessment of risk for COVID-19 but also may provide a significant technological enhancement to Johns Hopkins Medicine's telemedicine capabilities.

Primary Outcome

The principal outcome is the capability to calculate a reliable and clinically useful measure of blood oxygenation from video. Our objective is to quantify SpO2 from video within +/- 0.5% from clinical standard.
