Infants more severe BPD may still evolveinto progressive respiratory failure, or even death, as aresult pulmonaryhypertension that can result in cor pulmonale.The reported incidence varies widely thisvariation related to differences patient susceptibilityand management, but inconsistencies definitionalso accounts variation. The diagnostic criteria forBPD are based on dependency this varydue altitude, use other methods ofrespiratory support such continuous intermittentpositive airway pressure drugs caninfluence gas exchange, diuretics, respiratorystimulants corticosteroids.
