Lifelight Non-Invasive Blood Pressure and Heart Rate Validation Study

Lifelight is a novel, calibration-free, software-only medical device that contactlessly measures pulse rate and blood pressure by measuring remote photoplethysmography (rPPG) signals of a patient's face using a standard smartphone or tablet camera. By conducting this validation study we aimed to demonstrate the accuracy of Lifelight for classifying the full range of clinically relevant blood pressures as hypertensive or non-hypertensive and demonstrate its accuracy for measuring pulse rate and the blood pressure of people with blood pressures relevant to Stage 1 hypertension.
