What are normal and abnormal peak flow readings?
Normal peak flow readings vary, depending on your age, size, and sex. The range of normal peak flow readings is published on a chart, and doctors and nurses refer to the chart when they check your peak flow reading. In healthy people, peak flow readings vary slightly from time to time. The reading is often slightly higher in the evening compared with the morning.

Vad händer under ett astmaanfall?
Astma är ett vanligt tillstånd som påverkar de mindre luftvägarna (bronkiolerna). Ibland smalnar luftvägarna hos personer som har astma. De typiska symtomen är väsande andning, hosta, tryck över bröstet och andnöd. Graden av förträngning och hur länge varje episod varar kan variera mycket.

What is eosinophilic asthma and what makes it different?
For many people living with asthma, identifying triggers and getting the right treatment can make managing their condition easier on a day-to-day basis. But for people with eosinophilic asthma, symptoms and onset can be more unusual and harder to treat - and that in turn may make diagnosis and management more difficult.
