What is a common complication to monitor during oxygen therapy?

• A. Skin breakdown at device interface
• B. Hypertension due to infusion
• C. Increased hair growth
• D. Hypoglycemia

Answer: (A)

Skin irritation and breakdown at the device interface is the most common complication to monitor during oxygen therapy. The nasal cannula or face mask rests against the skin, and the combination of pressure, moisture from humidified gas, and friction can cause redness, irritation, and even pressure ulcers, especially at the nares, cheeks, and behind the ears. To prevent this, regularly inspect the skin around the interface, ensure a proper fit with gentle padding as needed, keep the skin clean and dry, and adjust the device if signs of irritation appear. If skin breakdown occurs, protect the area and reassess the delivery method with a clinician. Other issues listed aren’t typical complications of oxygen therapy.
