Pulse oximeter


Many doctors in emergency rooms are noticing a very concerning finding: Some COVID-19 patients have dangerously low levels of oxygen, but appear completely comfortable. This is being called “silent hypoxia.” While other conditions can cause silent hypoxia, the number of people with COVID-19 presenting this way is making some doctors rethink how we manage COVID-19 patients before they need emergency care.

Some are recommending that COVID-19 patients monitor their oxygen levels at home with a pulse oximeter. A pulse oximeter is a small device that clips onto your finger and measures the oxygen in your blood.
