Pulse Oximeter – Used To Measure Blood Oxygen Saturation And Pulse Rate. In 1977, Professor Sepp Sainaakon of the University of Oulu (Finland) invented the first battery-powered fingertip heart rate monitor. It is a small, practical and reliable non-invasive physiological monitoring device that can be used at home, thus avoiding a visit to the doctor. Based on the principle of two different light wavelengths, it is ideal for monitoring the health of all people – whether they exercise regularly, pay a lot of attention to physical activity, or suffer from various lung and vascular diseases. Most fingertip heart rate monitors are easy to use; just insert your finger into the clip. These devices have become particularly important during the Covid-19 pandemic, as they help diagnose when Covid-19 patients need urgent help. If Your Blood Oxygen Saturation Is Below 93%, Seek Medical Care Immediately. More and More Smartwatch Manufacturers Are Including Heart Rate Monitoring in Their Products. Some Models Are Also Water Resistant, Can Count Calories and Steps, Have a Stopwatch, Clock, Calendar, and Other Functions. This Compact Monitor Has Become an Indispensable Part of Modern Life, Helping You Balance Your Health and Well-Being.
