What is the best practice when using a pulse oximeter?

Best practices for using a pulse oximeter:

1. Clean the device and your finger. Wash your hands and the pulse oximeter with soap and water or an alcohol-based hand sanitizer. Dry your hands and the pulse oximeter thoroughly before use.

2. Place the pulse oximeter on your finger correctly. The pulse oximeter should be placed on your index or middle finger, with the sensor facing your palm. Make sure the pulse oximeter is snug but not too tight.

3. Keep your hand and finger still. Move the finger or shake your hand can cause inaccurate readings.

4. Wait for a stable reading. It may take a few seconds for the pulse oximeter to get a stable reading.

5. Review your reading. Once the reading is stable, look at the display to see your oxygen saturation level and heart rate.

6. Repeat the measurement if necessary. If you get a low reading or if you're not sure if the reading is accurate, repeat the measurement.

7. Talk to your doctor if you have concerns. If you have any concerns about your oxygen saturation level or heart rate, talk to your doctor.
