At birth, a decrease in pulmonary vascular resistance (PVR) is essential to facilitate pulmonary vascular perfusion as the infant establishes independent use of the lungs. • When PVR fails to decrease, hypoxemic respiratory failure (HRF) and pulmonary hypertension (PH) ensues. • A novel scoring tool was developed to characterize severity of HRF and PH in the setting of a critically ill newborn, accounting for level of hypoxemia and echocardiographic findings of PH.At birth, a decrease in pulmonary vascular resistance (PVR) is essential to facilitate pulmonary vascular perfusion as the infant establishes independent use of the lungs. • When PVR fails to decrease, hypoxemic respiratory failure (HRF) and pulmonary hypertension (PH) ensues. • A novel scoring tool was developed to characterize severity of HRF and PH in the setting of a critically ill newborn, accounting for level of hypoxemia and echocardiographic findings of PH.
