The digital health revolution has been lagging behind in at least one major field: blood pressure monitoring. For a very long time, there were no better solutions in the market than traditional cuffs. Even the first smartwatches (like the one I tested from Omron), were big and uncomfortable to wear. So it was time for companies to realise the future of BP monitoring lies in Photoplethysmography (PPG).
PPG is a non-invasive optical technique used to measure blood volume changes in the microvascular bed of tissue. It works by shining a light onto the skin and then measuring the variations in light intensity that result from changes in blood flow. As blood is pumped through the blood vessels, it absorbs and scatters the light, causing the intensity of the reflected or transmitted light to fluctuate. These fluctuations can be detected and analysed to provide information. Photoplethysmography is commonly used to monitor heart rate, blood pressure, and oxygen saturation levels in various medical settings.
