Bronchopulmonary dysplasia (BPD) is defined as a chronic lung disease that occurs when an infant requires oxygen support for at least 28 days after birth, with severity depending on the degree of oxygen dependence and mechanical ventilation support to maintain SpO2 above 89%.

Stem cell transplantation has been proven to be an effective treatment for bronchopulmonary dysplasia in premature infants. Vinmec has successfully performed this technique, helping premature infants recover their health.
