A pulse oximeter is a device used to estimate the amount of oxygen carried in the blood and pulse rate. It can be helpful for COVID-19 patients to monitor their illness at home.
The FDA suggests that changes or trends in oximeter measurements may be more relevant than relying on one single reading. Do not solely rely only on a pulse oximeter to assess your health condition or oxygen level.
If you are concerned about your pulse oximeter reading or if your symptoms are getting worse, contact your PH health care team.
Pulse oximeters cannot be used to diagnose COVID-19.  If you think you may have COVID-19, contact your PH care team or local health department about getting a diagnostic test for COVID-19.
