Pulse Oximeter Monitoring

<< RESPIRATORY


Considerations:

  • Provide student with as much privacy as possible given the urgency of the situation
  • Skin temperature may affect reading, the student’s finger should not be cold

Supplies:

  • Pulse Oximeter
  • Student’s Individualized Healthcare Plan (IHP)
  • Healthcare provider’s order
  • Parent/Guardian authorization form
  • Stethoscope

Procedure:

  1. Review healthcare provider’s order and student’s individualized healthcare plan
  2. Ensure proper documentation of parent/guardian authorization to perform this procedure
  3. Gather supplies and place on a clean surface
  4. Wash hands
  5. Explain procedure to student at a level he/she will understand
  6. Turn on pulse oximeter
  7. Select a distal extremity (usually a fingertip) that can be held still and is void of nail pol­ish, false nail, moisture, and sweat
  8. Minimize excessive environmental light
    • an accurate oxygen saturation reading requires that the pulse oximeter is able to consistently detect the student’s pulse
    • all pulse oximeters have some form of light signal or bar graph that correlates with detecting the pulse; and a consistent high level of detection for at least 20–30 seconds is necessary to de­termine an accurate reading
  9. Place pulse oximeter probe on distal extremity
  10. Check operation of the equipment (audible beep, fluctuation of bar of light or waveform on the face of oximeter)
  11. Make sure that the light emitting sensor and light receiving sensor are aligned opposite
  12. Wait 20-30 seconds
  13. Read oxygen saturation level on pulse oximeter
  14. Remove pulse oximeter probe
  15. Turn off pulse oximeter
  16. Follow healthcare provider’s orders with appropriate follow up care
  17. Wash hands
  18. Document oxygen saturation level in student’s healthcare record
  19. Follow up with parents/guardian and healthcare provider, as necessary
  20. Clean the pulse oximeter per manufacturer’s recommendations

Continuous Pulse Oximetry

  1. If the pulse oximetry is indicated to be continuous, the probe needs to be secured in place per manufacturer’s instructions
  2. An order for continuous pulse oximetry requires an oximeter with an alarm
  3. Alarm parameters are to be set per the healthcare provider’s order
  4. If the alarm sounds, the student requires immediate assessment to determine if it is a “false alarm” (commonly due to excessive movement) or a true emergency that reflects a sudden deterioration in the student’s respiratory status
