High-flow oxygen therapy, while beneficial in many clinical scenarios, can lead to specific complications if not administered appropriately. Oxygen toxicity is a significant concern, particularly when patients are exposed to high concentrations of oxygen for extended periods. Prolonged exposure to elevated oxygen levels can result in damage to the lungs and central nervous system, causing symptoms such as chest pain, difficulty breathing, or even seizures.

Additionally, hypercapnia, or an increase in carbon dioxide levels in the blood, can occur in patients with chronic obstructive pulmonary disease (COPD) who may be particularly sensitive to changes in their oxygen levels. Administering high-flow oxygen can suppress their respiratory drive, leading to insufficient expulsion of carbon dioxide, thereby exacerbating their condition.

In contrast, while the other options may involve potential health concerns, they are not directly linked to the use of high-flow oxygen therapy in the same manner. Understanding these complications emphasizes the importance of carefully monitoring patients receiving high-flow oxygen to avoid these adverse effects.
