Definitions of non-cardiac diagnoses in babies with test positive pulse oximetry

Congenital pneumoniaRaised inflammatory markers (CRP >10 mg/L)±positive culture, radiological changes on chest X-ray, oxygen requirement (for longer than 2 hours), antibiotics for ≥5 days
Meconium aspiration syndromeHistory of meconium staining of liquor, respiratory distress, oxygen requirement (for longer than 2 hours), radiological changes on chest X-ray
SepsisRaised inflammatory markers (CRP >10 mg/L)±positive culture, antibiotics for ≥5 days
TTN requiring oxygenTachypnoea with radiological changes of fluid retention, oxygen requirement (for more than 2 hours), no rise in inflammatory markers or positive culture
  • Congenital pneumonia, meconium aspiration syndrome or TTN requiring oxygen were classified as significant respiratory Illness. TTN - Transient tachypnoea of the newborn
