What is the target SpO2 range during oxygen therapy?

The target SpO2 range during oxygen therapy is generally established based on the needs of patients with various respiratory conditions. A target range of 88% to 94% is recommended as it helps ensure adequate oxygenation while minimizing the risk of oxygen toxicity and other complications, particularly in patients with chronic obstructive pulmonary disease (COPD) or other chronic lung diseases. This range balances the requirement for sufficient oxygen saturation to prevent hypoxemia with the concern of potential adverse effects from excessively high oxygen levels.

In patients with COPD, maintaining SpO2 above 88% prevents the risk of hypoxia while avoiding hyperoxia, which can worsen carbon dioxide retention and lead to respiratory acidosis. Therefore, the 88% to 94% target range aligns with clinical guidelines aimed at optimizing oxygen therapy outcomes for patients requiring supplemental oxygen. This careful balance is crucial for providing effective respiratory care while minimizing potential complications.
