Saturation oxygen pressure index for assessment of pulmonary disease in neonates on non-invasive ventilation.

This prospective observational study on 36 neonates aimed to estimate the correlation between the new Saturation Oxygen distending Pressure Index (SOPI) and Oxygenation index. SOPI had high correlation (r=0.94) with oxygenation index. SOPI of <2, 2, and 3.7 represented mild, moderate and severe pulmonary disease, respectively with high sensitivity and specificity.
