Oxygen: which cylinder, mask and flow work for you

Oxygen stops attacks for most people, but only when delivered properly. In a 2009 JAMA trial, 100% oxygen by mask at 12 L/min stopped or clearly eased 78% of attacks within 15 minutes (air: 20%). The 2023 European guideline advises at least 12 L/min and a non-rebreather mask. Pharmacy oxygen cans do not work for this: they hold far too little. Tell us: where did you get your cylinder or concentrator, which mask, what flow, and how many minutes until relief? Especially useful if you know how to get it in your country.
