What are the symptoms of bronchopulmonary dysplasia?

BPD or CLD: The classic diagnosis of bpd may be assigned at 28 days of life if the following criteria are met. Positive pressure ventilation during the first 2 weeks of life for a minimum of 3 days. Clinical signs of abnormal respiratory function. Requirements for supplemental oxygen for longer than 28 days of age. Chest radiograph with diffuse abnormal findings characteristic of chronic lung disease.

Breathing difficulty: Most infants who develop BPD are born more than 10 weeks before their due dates, weigh less than 2 pounds (about 1,000 grams) at birth, and have breathing problems. Infections that occur before or shortly after birth also can contribute to BPD.Infants that recover may have problems with asthma. More severe cases may require ventilatory support.
