What is the general oxygen target for COPD patients in many guidelines?

• A. 92–96% SpO2
• B. 80–85% SpO2
• C. 88–92% SpO2
• D. 95–100% SpO2

Answer: (C)

In COPD, oxygen therapy is aimed at keeping blood oxygenation adequate but not excessive, because too much oxygen can blunt the drive to breathe and worsen CO2 retention in chronic hypercapnic patients. That’s why a conservative target is taught: keep SpO2 in the 88–92% range. This range provides enough oxygen for tissues while minimizing the risk of hypercapnia and respiratory acidosis that can occur if oxygen levels are pushed higher. Use pulse oximetry to titrate oxygen flow to stay within this band—lower than 88% means you need more oxygen, higher than 92% means you should reduce it. Some patients with additional heart or lung conditions may require individual adjustments, but broadly, 88–92% is the general guideline.
