What is a potential hazard associated with long-term oxygen therapy?

Long-term oxygen therapy can lead to oxygen toxicity, which is a significant concern in patients requiring prolonged oxygen administration. This condition occurs when the body is exposed to high levels of oxygen for extended periods, resulting in harm to lung tissues and other organs. The lungs are particularly susceptible because excessive oxygen can generate reactive oxygen species, leading to cellular damage, inflammation, and even lung injury.

Oxygen toxicity can manifest as symptoms such as coughing, chest pain, and decreased lung function. It is essential for healthcare providers to monitor patients undergoing long-term oxygen therapy closely, adjusting the oxygen flow as necessary and ensuring that the concentration levels remain at a safe threshold to prevent these adverse effects.

While other options may reflect concerns that can arise in certain contexts, they do not represent the primary hazard associated with prolonged exposure to high concentrations of oxygen.
