Performing Pulse Oximetry: Monitoring Oxygen Levels

How do you perform pulse oximetry?

Performing pulse oximetry is a simple and non-invasive way to monitor oxygen levels in the blood. Here's a step-by-step guide on how to perform pulse oximetry:

What You Need:

  • A pulse oximeter device
  • Clean hands
  • Patient's finger (or other suitable body part)

Steps:

  1. Prepare the Equipment:

    • Ensure the pulse oximeter is clean and in working order.
    • Check that the batteries are charged or replace them if necessary.
  2. Prepare the Patient:

    • Ensure the patient is comfortable and seated if possible.
    • Make sure the patient's hand or finger is warm, as cold fingers can affect the accuracy of the reading.
  3. Clean Your Hands:

    • Wash your hands thoroughly to maintain hygiene.
  4. Turn On the Pulse Oximeter:

    • Press the power button on the pulse oximeter to turn it on.
  5. Insert the Finger:

    • Most pulse oximeters are designed to be used on the patient's finger. However, depending on the device, it can also be used on the earlobe or toe.
    • Slide the patient's finger (or the appropriate body part) into the pulse oximeter probe.
  6. Wait for the Reading:

    • Within seconds, the pulse oximeter will display two important measurements:
      • SpO2 (Oxygen Saturation): This is the percentage of oxygen in the patient's blood. A normal SpO2 reading is typically between 95% and 100%.
      • Pulse Rate: This is the patient's heart rate, measured in beats per minute (bpm).
  7. Record the Readings:

    • Take note of the SpO2 and pulse rate readings provided by the pulse oximeter.
  8. Interpret the Results:

    • A normal SpO2 reading indicates that the patient is adequately oxygenated.
    • If the SpO2 reading is significantly below 95%, it may indicate low oxygen levels (hypoxemia), and further medical attention may be necessary.
  9. Remove the Probe:

    • Gently remove the finger or body part from the pulse oximeter probe.
  10. Turn Off the Pulse Oximeter:

    • Press the power button to turn off the pulse oximeter when you're finished.
  11. Clean the Pulse Oximeter:

    • If the pulse oximeter is used on multiple patients, follow the manufacturer's instructions for cleaning and disinfecting it before and after each use.

Remember that while pulse oximetry is a valuable tool for monitoring oxygen levels, it is not a replacement for a comprehensive medical assessment. If you have concerns about a patient's oxygen levels or if readings are consistently outside the normal range, consult a healthcare professional for further evaluation and guidance.
