Which of the following is a common complication of long-term oxygen therapy?

Long-term oxygen therapy is essential for managing conditions that result in chronic hypoxia, such as COPD or other respiratory disorders. However, it carries risks, one of which is oxygen toxicity. This occurs when a patient receives oxygen concentrations that are too high for an extended period.

Oxygen toxicity can lead to cellular and tissue damage, particularly affecting the lungs and central nervous system. The body requires a delicate balance; while it needs oxygen to function, excess oxygen can lead to oxidative stress and inflammation. Symptoms of oxygen toxicity may include visual disturbances, nausea, muscle twitching, and in severe cases, seizures.

This understanding of oxygen toxicity highlights the importance of monitoring patients on long-term oxygen therapy to ensure they are receiving the appropriate concentrations and not exceeding safe levels.
