Treatment of asthma Treatment of asthma can be divided into - A) Treatment of chronic asthma B) Treatment of acute exacerbation - Treatment of mild, moderate or severe exacerbation Treatment of life-threatening exacerbation (status asthmaticus) Treatment of chronic asthma Treatment of chronic asthma is given to control asthma and to prevent acute exacerbation. Severity of asthma is classified on the basis of - The frequency of daytime symptoms      The frequency of nighttime symptoms  The degree of airflow obstruction (FEV1) Peak expiratory flow (PEF) variability For children less than 5 years of age, severity is classified on the basis of (1) and (2) only because young children cannot perform the manoeuvre required for lung function measurement ((3) & (4)). I) Mild intermittent                                   Symptoms for ≤ 2 days/week                            Symptoms for 5 ≤ 2 night/month                   FEV1 80%                                                  PEF variability < 20%            2) Mild persistent     Symptoms > 2days / week   PEF variability 20-30%      Symptoms >2 night / months     FEV1 80%         3) Moderate persistent                                 Day symptoms daily                                     Symptoms > I night/week                             FEV1 > 60% - < 80%                                  PEF variability >30%                                   A stepwise pharmacological therapy is indicated.   4) Severe persistent Continuous day symptoms Frequent night symptoms FEVi 60% PEF variability >30%
