For a stable postoperative patient, when should oxygen therapy be administered?

Oxygen therapy is critical in managing postoperative patients, especially to ensure that they maintain adequate oxygen saturation levels. The correct approach is to administer oxygen therapy when oxygen saturation levels drop below 92%. This threshold is commonly accepted in clinical practices because maintaining oxygen saturation above this level helps to ensure proper tissue oxygenation and can prevent complications associated with hypoxemia.

By closely monitoring the patient's oxygen saturation, caregivers can intervene appropriately when there is a deviation from the normal range. Starting oxygen therapy only at this point helps in tailoring the intervention to clinical needs rather than using a blanket approach that may not be necessary for every stable postoperative patient. This practice promotes patient safety, resource efficiency, and individualized care.
