Quizplus · Accepted Answer

Asthma is the result of hyperactive and hypersensitive bronchial tubes. The bronchial spasms of asthma can be triggered by many extrinsic (allergic) or intrinsic (nonallergic) factors, including stress, heavy exercise, infection, and inhalation of allergens or other substances. In a severe attack unresponsive to drug therapy, a condition called status asthmaticus may lead to fatal respiratory failure and thus the need for endotracheal intubation. The patient requires hospitalization for aggressive medical treatment and follow-up. Asthma is a chronic, reversible, obstructive disease caused by increased reactivity of the tracheobronchial tree to various stimuli. There are two major processes at work: constriction of the bronchioles and inflammation of the airway. It is a leading cause of chronic illness and school absenteeism in children.
