Applying a pulse oximeter is straightforward and non-invasive. It's a simple device used to measure the oxygen level in your blood.
Steps to Using a Pulse Oximeter
-
Preparation:
- Warm your hands: If your hands are cold, warm them first for a more accurate reading. (Reference 1)
- Rest: Find a comfortable position and rest for at least five minutes before taking a reading to ensure accurate results. (Reference 2)
-
Placement:
- Choose a finger: Place the oximeter clip on the fingertip of either your index (pointer) or middle finger. Avoid using a finger with nail polish or artificial nails. (Reference 3, Reference 7)
- Secure the clip: Gently but firmly attach the clip to your finger. Ensure a snug fit to allow proper light transmission through the fingertip. (Reference 5, Reference 6)
-
Reading:
- Remain still: Keep your finger still for at least a minute to obtain a stable and reliable reading. Movement can interfere with the accuracy of the measurement. (Reference 4)
- Observe the reading: The device will display the oxygen saturation level (SpO2) as a percentage and your pulse rate (bpm).
Understanding Pulse Oximetry
Pulse oximetry uses light beams to measure the amount of oxygen carried in your blood. The device shines red and infrared light through your fingertip, and based on how much light is absorbed, it estimates the percentage of oxygenated hemoglobin in your blood. (Reference 8, Reference 9, Reference 10) This is a non-invasive and painless procedure. (Reference 5, Reference 10).
