What therapeutic use of oxygen is indicated during a COPD exacerbation?

During a COPD exacerbation, the primary therapeutic use of oxygen is to maintain SpO2 levels above 90%. Patients with chronic obstructive pulmonary disease often experience hypoxia, which can lead to significant complications if not addressed. Oxygen therapy is critical in managing their condition, as it helps ensure that the body's tissues receive adequate oxygen, facilitating normal cellular function and preventing further deterioration of the patient’s health.

Maintaining oxygen saturation levels above 90% is important because lower levels can lead to respiratory distress, confusion, and increased strain on the heart and lungs. Therefore, administering oxygen to achieve and sustain these saturation levels is a central goal in the management of COPD exacerbations.

Oxygen does not serve as a pain reliever, enhance exercise tolerance directly, or act as an agent to prevent infections. While improving oxygenation may contribute to better function and ability, the immediate and recognized goal during an exacerbation involves correcting hypoxemia.
