While oxygen therapy is generally safe, there are potential complications nurses should be aware of:
Oxygen Toxicity: Prolonged exposure to high levels of oxygen can cause lung damage. Skin Breakdown: Pressure from masks or cannulas can cause sores, particularly in patients with fragile skin. Dry Mucous Membranes: High-flow oxygen can dry out the nasal passages and mouth. Hypoventilation: Particularly in COPD patients, too much oxygen can suppress the drive to breathe. Fire Hazard: Oxygen supports combustion, so care must be taken to avoid open flames or sparks near the oxygen source.
