مريض ربو أفضل قراءة شخصية لذروة التدفق عنده ٤٠٠ لتر/دقيقة. بعد بخاخ السالبيوتامول صارت القراءة ٢٦٠ وما زال عنده صفير خفيف. ماذا تعني حسب خطة الربو؟

An asthmatic client’s personal-best peak flow is 400 L/min. After using salbutamol, his reading is 260 and he still has a mild wheeze. What does this mean on his action plan?

1. Red zone: call an ambulance now because it is an emergency
2. Yellow zone: repeat the reliever per the plan and contact his provider if no improvement
3. Green zone: continue his usual medicines without any change
4. Yellow zone: stop his inhaled steroid until the reading improves

Answer: B) Yellow zone: repeat the reliever per the plan and contact his provider if no improvement. 260 of 400 is 65%, which is the yellow zone (50–79%): an attack needing the reliever per plan and provider review if he does not return to green. Green is 80% or more, red is under 50%, and stopping the inhaled steroid during an attack is wrong.
