Amid the ongoing COVID-19 pandemic, some patients have been monitoring the level of oxygen in their blood using pulse oximeters, which can be purchased at different pharmacies and retail chains, including Amazon, Target, Walgreens and CVS.
The American Lung Association explains: "A pulse oximeter measures the level of oxygen saturation in your red blood cells. This handy tool, which is usually clipped to the end of your finger or earlobe, has gained attention during the COVID-19 pandemic as a potential tool to identify hypoxia (low blood oxygen saturation) which is one troubling sign of severe illness caused by COVID-19.
