A 22-year-old with asthma has a personal best peak flow of 500. For two days after a cold he has had night cough and mild wheeze; today his reading is 275 (55% of best) and he speaks in full sentences. According to the colour action plan, which zone is he in and what should he do?

1. Red zone: rest is enough and recheck tomorrow
2. Yellow zone: stop all preventer inhalers
3. Green zone: continue usual medicines only
4. Yellow zone: use the reliever and follow his action plan

Answer: D) Yellow zone: use the reliever and follow his action plan. Green is 80–100%, yellow 50–79% needing the reliever and action plan, red below 50% needing emergency care. Preventers are not stopped.
