Which is NOT a goal of oxygen therapy?

Oxygen therapy is primarily aimed at improving tissue oxygenation, decreasing cardiac workload, and decreasing the work of breathing in patients with conditions that cause hypoxia. It is designed to enhance the delivery of oxygen to tissues, thereby supporting cellular function and reducing the strain on the heart, which is essential, particularly in patients with respiratory or cardiovascular issues.

Choosing hypercapnia, or an increased level of carbon dioxide in the blood, as a goal of oxygen therapy is a misunderstanding of the therapy's intent. While managing oxygen levels, especially in patients with chronic obstructive pulmonary disease (COPD) or conditions that can lead to hypoventilation, careful monitoring is critical to avoid raising carbon dioxide levels. Oxygen therapy itself is not intended to increase the risk of hypercapnia; instead, it should be monitored to maintain a balance that prevents this condition. Thus, this choice accurately reflects a misconception about the goals of oxygen therapy.
