Why You Should Never Tape a Pulse Oximeter: Inaccurate Readings and Patient Discomfort

Never tape a pulse oximeter probe to the patient. Taping:

• Distorts light transmission → falsely low or erratic SpO2 readings.
• Causes skin traction, irritation, and discomfort.

Correct Use

• Place on clean, dry finger (or toe/earlobe per device).
• Ensure snug but not tight fit—no venous congestion.
• Secure with device's built-in clip or adhesive designed for oximetry.
• Monitor for sudden changes; troubleshoot or replace if readings unreliable.

Accurate oximetry depends on proper probe-skin interface.
