All infants should be transferred to a level IV neonatal intensive care unit where high-frequency ventilation (HFV) and inhaled nitric oxide (iNO) are available. If the neona...
PPHN usually resolves either spontaneously or as the underlying parenchymal lung disease improves.
Survival rate is good even for neonates who receive ECMO. Survival rate and inci...

Q: Does iNO improve outcome in newborns with severe PPHN?
A: Yes. Although iNO has not been shown to reduce mortality, it has been shown to decrease the need for ECMO by 40% and reduce the length o...

FIGURE 1.32. A 60-year-old man with pulmonary hypertension due to chronic liver disease. A: On the frontal chest radiograph, the main pulmonary artery is enlarged (arrow). The right interlobar pulmonary artery is enlarged, measuring 20 mm. The normal value is 17 mm (arrows). B: On the lateral view, the left pulmonary artery is enlarged, measuring 23 mm, compared with a normal value of 20 mm.
