مريض على أكسجين منزلي من مُكثف أكسجين، ويسأل عن انقطاع الكهرباء. ما النصيحة الأهم؟

A client uses a home oxygen concentrator and asks about power cuts. What is the key advice?

1. A ready backup cylinder and registering with the supplier
2. No plan is needed because power cuts are rare
3. Stop the oxygen during a cut until power returns
4. Run the concentrator from a generator inside the closed bedroom

Answer: A) A ready backup cylinder and registering with the supplier. Concentrators need electricity, so the client needs a backup cylinder and emergency plan, with his needs registered with providers. Running a generator indoors risks carbon monoxide poisoning.
