A pulse oximeter is a vital medical device that gained widespread attention during the COVID-19 pandemic. It measures the oxygen saturation level in the blood, helping to monitor respiratory health. COVID-19, known for causing respiratory complications, often leads to reduced oxygen levels, sometimes without noticeable symptoms. The pulse oximeter became an essential tool for early detection of "silent hypoxia," allowing timely medical intervention and saving lives. Its ease of use and ability to provide real-time results made it a critical resource for both healthcare professionals and individuals managing COVID-19 at home.
