Prolonged exposure of immature lungs to hyperoxia contributes to neonatal lung injury and airway hyperreactivity. We have previously demonstrated that neonatal exposure of rat pups to ≥95% O2 impairs airway relaxation due to disruption of nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) signaling.
