How is it that lung compacity in asthma is lower than non asthma people?
A doctor has provided 1 answer
Reduced Flows: People with asthma tend to have reduced airflow because their small airways are narrowed leading to slower rates of airflow and more air trapping. When given a bronchodilator, this airflow obstruction can be reversed in most asthmatics that have uncontrolled airway inflammation. Total lung capacity is not usually affected but they can have air trapping leading to increased residual volume in lungs.
