What is the recommended SpO2 target range for a COPD patient who requires oxygen therapy?

• A. 95-100%
• B. 88-92%
• C. 92-96%
• D. 85-90%

Answer: (B)

In COPD patients who need supplemental oxygen, the goal is to balance adequate oxygenation with avoiding excessive oxygen that can worsen CO2 retention. Many people with chronic CO2 retention don’t tolerate very high oxygen levels well, because higher oxygen can blunt the drive to breathe and increase the risk of hypercapnia and acidosis. That’s why the target SpO2 is kept in the lower range, specifically 88-92%. This range provides enough oxygen to prevent hypoxemia while minimizing the chance of CO2 retention. Targets much higher, like the mid-to-high 90s or 100%, raise the risk of CO2 retention; targets a bit lower, like 85-90%, can put the patient at risk for hypoxemia. Monitor with pulse oximetry and adjust the oxygen flow to stay within 88-92%, reassessing as the patient’s condition changes or based on arterial blood gas results.
