What is the target SpO2 range for patients with chronic obstructive pulmonary disease (COPD)?

The target SpO2 range for patients with chronic obstructive pulmonary disease (COPD) is generally set between 88-92%. This range is specifically chosen for COPD patients because these individuals often have compromised respiratory function and can be sensitive to fluctuations in oxygen levels. Maintaining oxygen saturation within this target range helps to ensure that the patients are adequately oxygenated while minimizing the risk of hypercapnia (elevated carbon dioxide levels in the blood), which can occur if oxygen flow is too high.

Higher target levels, such as those above 92%, could lead to an increase in carbon dioxide retention and worsened respiratory acidosis in patients with COPD. Therefore, the recommended SpO2 range of 88-92% is a balance that supports sufficient oxygenation without compromising respiratory drive. This careful management is crucial for maximizing patient safety and comfort while managing the effects of COPD.
