Correct answer: D — 100% oxygen at 12–15 L/min via a non-rebreathable mask for 15–20 minutes

NICE CG150 recommends 100% oxygen at a flow rate of 12–15 L/min delivered via a non-rebreathable mask for 15–20 minutes for acute cluster headache attacks. It is effective in approximately 80% of attacks. The patient should be prescribed a home oxygen cylinder with an appropriate non-rebreathable mask and high-flow regulator. Low-flow oxygen or nasal cannulae are ineffective. A: Nasal cannulae at 2 L/min are ineffective. C: Nebulised oxygen is not a standard preparation. D: Low-flow oxygen is ineffective. E: Continuous oxygen is not needed — it is for acute attacks only.
