Asthma
Effects of Particle Size in Small Airways Dysfunction
The airways in the lungs get smaller the further into the lungs they go. Most simple measurements of lung function only reflect the larger 'central' airways and do not provide information on the smaller 'peripheral' airways.

- Testing
- Formoterol, Salmeterol
