What are some potential complications of oxygen therapy?

Oxygen therapy, while critical for treating various respiratory conditions, does introduce some potential complications. The correct answer highlights oxygen toxicity and dry mucous membranes as significant concerns associated with the therapeutic use of oxygen.

Oxygen toxicity occurs when an individual is exposed to high concentrations of oxygen for extended periods. This can lead to cellular damage, primarily affecting the lungs and central nervous system. Consequently, it can result in symptoms such as chest pain, coughing, and pulmonary edema, which can worsen a patient's condition rather than improve it.

Dry mucous membranes are another common side effect, especially in patients who are receiving oxygen through high-flow systems or non-humidified sources. Prolonged dryness can lead to discomfort, potential bleeding, and increased risk of infections in the respiratory tract due to damage to the mucosal barrier.

Understanding these complications is essential for healthcare providers to monitor their patients effectively and take preventive measures, such as using humidifiers or adjusting oxygen concentrations based on patient response. This ensures that the benefits of oxygen therapy outweigh the risks associated with its administration.
