All procedures have some risks. The risks of this procedure may include:

·         Incorrect reading if the probe falls off the earlobe, toe, or finger

·         Skin irritation from adhesive on the probe

Your risks may vary depending on your general health and other factors. Ask your healthcare provider which risks apply most to you. Talk with him or her about any concerns you have.

How do I get ready for pulse oximetry?

Your healthcare provider will explain the procedure to you. Make sure to ask any questions you have about the procedure. If a finger probe is to be used, you may be asked to remove fingernail polish.

Your healthcare provider may have other instructions for getting ready.

What happens during pulse oximetry?

You may have your procedure as an outpatient. This means you go home the same day. Or it may be done as part of a longer stay in the hospital. The way the procedure is done may vary. It depends on your condition and your healthcare provider's methods. In most cases, pulse Oximeter will follow this process:

1.      A clip-like device called a probe will be placed on your finger or earlobe. Or, a probe with sticky adhesive may be placed on your forehead or finger.

2.      The probe may be left on for ongoing monitoring.

3.      Or it may be used to take a single reading. The probe will be removed after the test.\

What happens after pulse oximetry?

You can go home after the test unless you are in the hospital for another reason. You may go back to your normal diet and activities as instructed by your healthcare provider. Your healthcare provider may give you other instructions after the procedure.
