Childhood asthma is a common pulmonary disease. It manifests as recurrent coughing, wheezing, and difficulty breathing, along with reversible, obstructive respiratory diseases with airway hyperreactivity. This disease poses a significant health risk to children and is a commonly seen chronic respiratory condition with a high incidence, often characterized by recurrent attacks over a chronic course. If the condition is severe, it can affect the child's learning, activities, daily life, and can also impact the child's growth and development. If the child's treatment is delayed or inappropriate, it can eventually develop into adult asthma, becoming chronic and intractable. Therefore, this disease must be diagnosed and treated promptly, as it is a relatively common condition.
