About this trial
Around 50% of infants born extremely preterm develop a chronic lung disease known as bronchopulmonary dysplasia of which some infants will also develop pulmonary hypertension of which 50% of children will die before the age of 2. Physicians are currently limited in their ability to select the most appropriate oxygen targets that will improve outcomes in infants with this condition. This clinical trial will determine whether using different amounts of oxygen improve outcomes in infants with this disease.
