High-resolution CT scan of the thorax obtained during expiration demonstrates a mosaic pattern of lung attenuation in a patient with asthma. Because of the small size (1-20 μm) of dander, saliva, urine, or serum proteins of cats and other animals, these allergens are predominantly airborne indoor allergens. [Medline]. Peak-flow meters should be used to allow objective evaluation of symptoms and interventions. Control of factors contributing to asthma severity is an essential component in asthma treatment. Particles smaller than 1 μm are too small to be effective because they move in the airways by Brownian motion and do not reach the lower airways. [Medline].
