Inclusion Criteria

Any intubated neonate more than or equal to 34 w gestational age, within first 7 days of life, having echocardiographic features (given below) along with any one of the following clinical features of PPHN:

oxygenation index (OI) greater than 10;

fractional of inspired oxygen greater than 0.30; OR labile SpO2 with differential pre- and post-ductal SpO2 greater than 5%

Dilated RA and RV.

)
