مريض COPD يسأل عن السفر بالطائرة وهو يستخدم أكسجيناً في البيت. ما النصيحة الصحيحة؟

A COPD client on home oxygen asks about flying. What is the correct advice?

1. No oxygen is needed in flight because cabin pressure equals ground level
2. See his doctor before travel and arrange in-flight oxygen with the airline in advance
3. Stop oxygen the day before so his lungs adapt
4. Pack his own cylinder in his luggage without telling anyone

Answer: B) See his doctor before travel and arrange in-flight oxygen with the airline in advance. Cabin pressure is lower than at ground level, so saturation falls in lung disease. The doctor assesses in-flight oxygen needs and approved devices are arranged with the airline in advance.
