Covid is now for most people 'old news' and please can we move on. But for some of us, that were affected by it and even lost someone precious, Covid is a scary reality. Covid isn't finished with us and isn't going to disappear. Many people with COVID-19 have low levels of oxygen in their blood, even when they feel well. Low oxygen levels can be an early warning sign that medical care is needed. I checked my oxygen levels with my M4 Smart wristband and didn't need to go to the doctor to have it measured.
