Post-ROSC oxygen — DipIMC MCQ

Correct answer: B — Titrate oxygen to maintain saturations around 94-98%

Option B is correct because Post-ROSC oxygen should be titrated to avoid both hypoxaemia and unnecessary hyperoxaemia. Option E is less appropriate because watchful waiting risks deterioration or delays definitive care; option C is less appropriate because the clinical risk exceeds that destination or timeframe. Option D is less appropriate because it is plausible in a different scenario but suboptimal for the features described; option A is less appropriate because analgesia is important but not sufficient as the primary intervention. Clinical pearl: in DipIMC-style questions, the best answer is the intervention that changes outcome earliest in the pre-hospital phase.
