What should I do if my pulse oximeter is not showing any results after performing the test?

When this happens, it is usually because your finger was not inserted correctly into the pulse oximeter. Try re-inserting your finger and making sure to place your finger in the device nail side down and to keep your finger very still during the reading. Complete another reading to get the correct results. See below for more details on how to correctly insert your finger into the pulse oximeter.
