Explore Bronchopulmonary Dysplasia
Bronchopulmonary dysplasia (BPD) develops as a result of an infant's lungs becoming irritated or inflamed.
The lungs of premature infants are fragile and often aren't fully developed. They can easily be irritated or injured within hours or days of birth. Many factors can damage premature infants' lungs.
Newborns who have breathing problems or can't breathe on their own may need ventilator support. Ventilators are machines that use pressure to blow air into the airways and lungs.
Although ventilator support can help premature infants survive, the machine's pressure might irritate and harm the babies' lungs. For this reason, doctors only recommend ventilator support when necessary.
Newborns who have breathing problems might need oxygen therapy (oxygen given through nasal prongs, a mask, or a breathing tube). This treatment helps the infants' organs get enough oxygen to work well.
However, high levels of oxygen can inflame the lining of the lungs and injure the airways. Also, high levels of oxygen can slow lung development in premature infants.
Infections can inflame the lungs. As a result, the airways narrow, which makes it harder for premature infants to breathe. Lung infections also increase the babies' need for extra oxygen and breathing support.
Studies show that heredity may play a role in causing BPD. More studies are needed to confirm this finding.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for Bronchopulmonary Dysplasia, visit www.clinicaltrials.gov.

Researcher Brings Medicine One Step Closer to Widely Available Cure for Sickle Cell Disease
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
