What might indicate a need to discontinue oxygen therapy?

Discontinuing oxygen therapy is often considered when a patient's condition improves and their oxygen saturation levels reach or exceed the target range for safe oxygenation. Decreased oxygen saturation levels indicate that the patient may be unable to maintain adequate oxygen levels in the blood, which is a clear sign that oxygen therapy is necessary. Conversely, if a patient exhibits stable or improved oxygen saturation, it suggests their respiratory status is adequate enough to potentially discontinue supplemental oxygen without the risk of hypoxemia.

The other statements provide information that would generally indicate the continuation of oxygen therapy rather than discontinuation: stable respiratory rates and stable vital signs suggest that the patient is stable overall and may not necessitate changes. Increased work of breathing indicates a higher demand for oxygen, requiring continued support until breathing ease is restored. Thus, monitoring oxygen saturation levels is crucial in guiding whether to support treatment or make adjustments in oxygen therapy.
