Correct answer: C — Delay departure until adequate oxygen supply and reserve are secured

Transport oxygen planning must include loading, unloading, delays, higher consumption during deterioration and a reserve. A plan that covers only nominal flight time is unsafe. Reducing oxygen below clinical need or extubating for logistics is inappropriate. The pearl is that retrieval medicine is logistics under physiological risk.
