Obstructive ventilatory defects in pediatrics

Obstructive airway syndromes are the most common cause of respiratory symptoms in infants and children. By the age children are capable of performing spirometry correctly (developmental age > 6 yr) most congenital syndromes and severe diseases (cystic fibrosis) have been detected, but this is not invariably the case! As asthma is so common it is not exceptional for children to have a second respiratory disorder. One way to categorize obstructive syndromes is by the site of the abnormality.

High extrathoracic disorders

Central (intrathoracic) disorders

Peripheral disorders
