Objective To evaluate the association between the Respiratory Severity Score (RSS) and Oxygenation Index (OI) in intubated, mechanically ventilated, newborn infants. Study Design In a retrospective cohort study (December 2006 to June 2010) medical records of all infants who were admitted to our Neonatal Intensive Care Unit (NICU) and required invasive mechanical ventilation were reviewed for patients' demographics, ventilator settings, and arterial blood gas (ABG). Results During the study period 2,332 infants were admitted to our NICU, and 425 infants were intubated and had an ABG with a gestational age of 30.5 ± 4.9 weeks and a birth weight of 1,635 ± 923 g (mean ± standard deviation). There was a strong association between RSS and OI in infants with oxygen saturation (SaO 2 ) between 88% and 94% (R 2 = 0.982, n = 101; P < 0.001). Conclusion In intubated newborn infants, there is a strong association between RSS and OI at SaO 2 between 88% and 94%. Pediatr Pulmonol. 2013; 48:364–369. © 2013 Wiley Periodicals, Inc.
