What is the guideline regarding renewing home oxygen prescriptions after hospitalisation for acute illness?

• A. Always renew if previously prescribed
• B. Not renewed without assessment for ongoing hypoxaemia
• C. Renew only if SpO2 below 90% on room air
• D. Renew only if symptoms worsen

Answer: (B)

After a hospitalization for an acute illness, oxygen needs should be reassessed rather than renewed automatically. The decision to continue or restart home oxygen depends on whether there is ongoing hypoxaemia. This means checking oxygenation on room air at rest and, if indicated, during exertion or sleep to see if desaturation persists. If resting SpO2 is normal and there is no evidence of persistent hypoxaemia, oxygen can be discontinued. If hypoxaemia persists on room air, then home oxygen should be renewed or continued. This approach makes sense because oxygen therapy is driven by current oxygenation status, not just past need or symptoms. Relying on automatic renewal risks ongoing, unnecessary use, while basing renewal solely on symptoms or a fixed threshold without re-evaluation can miss patients who are still hypoxaemic or, conversely, keep therapy longer than needed.
