Bronchopulmonary dysplasia

  • Definition

    Bronchopulmonary dysplasia (BPD) is a chronic lung condition that affects newborn babies who were either put on a breathing machine after birth or were born very early (prematurely).


    Alternative Names

    BPD; Chronic lung disease - children; CLD - children


    Causes, incidence, and risk factors

    Bronchopulmonary dysplasia (BPD) occurs in severely ill infants who have received high levels of oxygen for long periods of time or who have been on a breathing machine ( ventilator).

    It is more common in infants born early (prematurely), whose lungs were not fully developed at birth.

    Risk factors include:

    • Congenital heart disease
    • Prematurity, usually in infants born before 32 weeks of gestation
    • Severe respiratory or lung infection
    • Other severe illness in the newborn that needs to be treated with oxygen or a ventilator

    The risk of severe BPD has decreased in recent years.
