How do I prepare for a pulse oximetry test?

ANSWER

You don't have to do anything special to get ready for this test.

The test results might not be correct if your fingers are dirty, your nails are too long, or if your nails are covered in dark polish. The nurse may ask you to wash your hands, take your nail polish off, or trim the nail on the finger they're testing.

Ask your nurse if you have any questions or concerns.
