What is a common side effect of high levels of oxygen therapy?

Oxygen-induced hypercapnia is a notable side effect associated with high levels of oxygen therapy, particularly in patients with chronic obstructive pulmonary disease (COPD) or other conditions that lead to respiratory failure. In these patients, the body relies on a low level of oxygen to stimulate the respiratory drive. When high levels of oxygen are administered, it can reduce this drive and lead to a decreased respiratory rate or hypoventilation, consequently causing carbon dioxide retention (hypercapnia). This scenario highlights the delicate balance required in managing oxygen therapy, especially in those with chronic respiratory conditions.

The other side effects, such as respiratory alkalosis, hypoxemia, and bronchospasm, may occur due to various factors but are not as directly linked to high levels of oxygen therapy in a typical clinical context. Respiratory alkalosis, for example, often arises from hyperventilation rather than oxygen therapy itself. Hypoxemia refers to insufficient oxygen levels in the blood, which would generally be a symptom that oxygen therapy aims to alleviate, not a direct complication of it. Lastly, bronchospasm is typically more associated with irritants or allergens rather than the administration of oxygen. Understanding the implications of oxygen therapy is crucial in respiratory care to avoid potential complications while
