Development of a blood pressure monitoring system based on smart-camera video recording
Hypertension causes 7.5 M deaths worldwide with no warning signs or symptoms and occurs in more than two thirds of individuals over the age of 65. Hypertension is a major risk factor for coronary heart problems including ischemic and hemorrhagic strokes, kidneys failure, and visual impairment. The most impactful action against hypertension is frequent blood pressure (BP) measurements, which assure early intervention and its successful management.
Ovid BP proposes an innovative technology to allow comprehensive BP detection and management via patented software. This software leverages today’s advanced smartphone camera technology to capture the biomarkers required to determine a patients’ BP. The solution is empowered by an algorithm that estimates BP from the heart’s QRS signal, which is specifically captured through analysis of the patients’ Vertical Head Movement (VHM). Additionally, it allows to observe the rate of facial blood flow through the well-understood practice of video plethysmography (vPPG).
With this data the system can produce the Instantaneous Hearth Rate Period (THRi) and Instantaneous Pulse Transit Time (PTTi). These are then analyzed by a cloud-based algorithm yielding systolic and diastolic blood pressure as well as heart rate in a matter of moments.
