What is one major risk of administering too much oxygen?

Administering too much oxygen can lead to oxygen toxicity, which is a significant risk associated with excessive oxygen exposure. Oxygen toxicity occurs when high concentrations of oxygen are breathed in for prolonged periods, leading to the generation of reactive oxygen species. These compounds can cause damage to lung tissues and other organs due to oxidative stress. Symptoms of oxygen toxicity may include coughing, difficulty breathing, chest pain, and in severe cases, it can result in a condition known as acute respiratory distress syndrome (ARDS).

The management of oxygen therapy requires careful monitoring of the oxygen concentration to prevent such adverse effects. While the other options present possible issues related to oxygen therapy, they do not encompass the critical and potentially severe consequences of oxygen toxicity that can arise from high levels of oxygen administration over time.
