Pathophysiology
This leads to air trapping, increased dead space and hyperinflation
Allergic or extrinsic asthma is frequently associated with personal or family history of allergic diseases such as eczema, rhinitis and urticaria
Increased respiratory resistance and also bronchospasm, airway inflammation, mucosal edema and mucus plugging.
-
-
Characterized by inflammation of the airways with an abnormal accumulation of inflammatory cells in the bronchioles.
