What is a common side effect of oxygen therapy in long-term use?

Long-term use of oxygen therapy can lead to oxygen toxicity, a condition that occurs when the body is exposed to elevated levels of oxygen for extended periods. While oxygen is critical for cellular metabolism, when concentrations exceed normal atmospheric levels, particularly above 21% for prolonged durations, it can result in harmful effects.

Oxygen toxicity primarily affects the lungs and central nervous system. In the lungs, it can lead to symptoms such as coughing, chest pain, and difficulty breathing due to the accumulation of fluid, inflammation, and cellular damage. In the central nervous system, it can cause symptoms ranging from visual disturbances to seizures and other neurological issues.

Monitoring patients receiving long-term oxygen therapy is essential to prevent these adverse effects. Adjustments to therapy may be necessary to ensure that oxygen levels remain within a safe range, highlighting the importance of patient education regarding the signs and symptoms of oxygen toxicity so that they can seek prompt medical attention if they experience any troubling symptoms.
