شاب عمره ٢١ سنة، طويل ونحيف ويدخن، تعافى من استرواح صدري تلقائي في اليمين عولج بأنبوب صدر قبل أسبوع، والأشعة الأخيرة تظهر تمدد الرئة. يخطط لرحلة طيران بعد ٤ أيام ويحب الغوص. ما النصيحة الصحيحة غالباً؟

A tall, thin 21-year-old smoker recovered from a right spontaneous pneumothorax treated with a chest drain a week ago; the latest X-ray shows full re-expansion. He plans a flight in 4 days and enjoys scuba diving. What is the usual correct advice?

1. Use oxygen on the plane so that he can then dive safely
2. There are no restrictions now that the lung is fully up
3. Delay flying until cleared; no diving without review
4. Fly tomorrow and go diving normally after a week

Answer: C) Delay flying until cleared; no diving without review. Pressure changes in flying and diving can cause recurrence or tension. Flying is usually delayed until imaging confirms resolution for a period, and diving is generally avoided after pneumothorax unless surgically treated and specialist-cleared.
