There is limited information concerning the exercise performance of long-term survivors of bronchopulmonary dysplasia (BPD), and much of what is available pertains to those with relatively mild disease. The present study was undertaken to describe exercise responses in patients with a history of severe BPD, defined as those patients with a clinical and radiographic diagnosis of BPD who required supplemental oxygen at least until they were 44 wk postconceptual age and who were discharged home on oxygen. Fifteen children with a history of severe BPD were matched for gestational age with 15 children who had previously had respiratory distress syndrome but who did not develop BPD (Prem). These Prem control children were subsequently compared with 13 healthy control children born at term (Control) who were of similar postnatal age. Participants underwent pulmonary function testing, progressive exercise testing on a cycle ergometer, and a steady-state exercise test with cardiac output determined by CO2-rebreathing. Despite the patients with BPD having a lower FEV1 than those in the Prem group, who had lower values than the Control group (BPD, 64 +/- 21%; Prem, 85 +/- 11%; Control, 95 +/- 8%), the exercise capacity did not differ between the BPD and the Prem and between the Prem and the Control groups (BPD, 84 +/- 15%; Prem, 81 +/- 17%; Control, 91 +/- 12%). However, the BPD patients used a greater percentage of their ventilatory reserve (VEmax/40 FEV1: BPD, 93 +/- 20%; Prem, 67 +/- 12%; Control, 59 +/- 13%). Of the four patients with BPD who had significant oxygen desaturation with exercise, three had the lowest values for FEV1. Cardiac output was appropriate for oxygen consumption in most patients.
