Once we breathe in, our lungs fill with oxygen, which is distributed to our purple blood cells for transportation all through our bodies. Our bodies want a lot of oxygen to function, and healthy individuals have at the very least 95% oxygen saturation all the time. Conditions like asthma or COVID-19 make it tougher for our bodies to absorb oxygen from the lungs.

In a clinic, docs monitor oxygen saturation utilizing pulse oximeters - those clips you set over your fingertip or ear. But monitoring oxygen saturation at home a number of instances a day may help patients keep an eye on COVID signs, for example.
