Asthma is a common respiratory disease among children, characterized by coughing, wheezing, tightness of breath, and prolonged respiratory phases. Children who have been diagnosed with asthma are evaluated according to the frequency and degree of their wheezing episodes as well as their lung function. There are four levels of assessment, as follows: 1. Level 1 is asymptomatic between attacks, with nocturnal attacks less than twice a month, and pulmonary function tests suggesting normal lung function; 2. Level 2 is greater than one attack per week and less than one attack per day, with attacks that may interfere with their activities and sleep. Nocturnal seizures were greater than 2 per month, and a pulmonary function test was abnormal; 3. Grade 3 was daily symptoms and seizures that interfered with the child’s activities and sleep. Nocturnal episodes are greater than 1 per week, and pulmonary function tests are also abnormal; 4. Grade 4 is a child with persistent and frequent symptoms of wheezing, marked limitation of physical activity, frequent nocturnal episodes, and markedly abnormal pulmonary function tests.
