What is the SpO2 level typically associated with discontinuation of O2 therapy?

The typical SpO2 level associated with the safe discontinuation of oxygen therapy is generally around 92%. This level indicates that the patient’s oxygen saturation is within an acceptable range to maintain adequate tissue oxygenation without supplemental oxygen. A saturation of 92% is often considered a threshold where patients can be monitored for adequate respiratory function while minimizing unnecessary oxygen exposure.

Levels below this, such as 90% and 88%, are usually regarded as requiring continued oxygen support to ensure the patient is not at risk for hypoxemia. Meanwhile, a SpO2 of 94% may still prompt healthcare providers to consider extending oxygen therapy, particularly if there are other underlying health concerns or if the patient's condition is unstable. Thus, 92% serves as a balanced guideline for clinicians to evaluate when to safely discontinue supplemental oxygen therapy.
