Asthma severity, classification

Classification of asthma severity is based on daytime and nighttime symptoms, physical activity, lung function, variability in peak expiratory flow (PEF), and use of reliever medications. 

In chronic asthma, classification of asthma severity is based on daytime and nighttime symptoms, physical activity, lung function (PEF or FEVfi, PEF variability, and reliever medication use. Because lung function is difficult to measure in preschool children (children 5 years of age or younger), it cannot be used to classify disease severity in this age group. Chronic asthma is classified as mild intermittent asthma, or mild, moderate or severe persistent asthma (Table 11-1).

The ARIA paper [1] summarizes current knowledge on rhinitis and its link to asthma and features several main issues, presenting a new classification of rhinitis with reference to a similar classification as is currently used for asthma. Because of the long-term exposure to seasonal allergens in some countries and the seasonal variations also observed in mite allergen exposure [2], it was decided that the terms seasonal and perennial would not be very helpful for any decision in terms of treatment. Furthermore, seasonal and perennial...
