What is the target oxygen saturation (SpO2) range for a patient with COPD or chronic bronchiectasis?

For patients with COPD (Chronic Obstructive Pulmonary Disease) or chronic bronchiectasis, maintaining an appropriate oxygen saturation level is crucial for effective management of their condition. The target oxygen saturation range of 88-92% is considered optimal for these patients. This range helps to ensure that sufficient oxygen is delivered to the tissues while minimizing the risks of oxygen toxicity and hypercapnia, which can result from excessive oxygen use.

In COPD patients, high levels of oxygen saturation can suppress the respiratory drive, leading to an increase in carbon dioxide levels in the blood. Therefore, targeting a lower saturation range allows healthcare providers to manage the patient's oxygenation while considering their unique physiology and potential respiratory complications. Over-targeting oxygen saturation can lead to adverse effects, making 88-92% a more appropriate choice for this population.
