Which of the following statements about PPHN is correct?

PPHN is defined as a failure in newborn circulatory adaptation

PPHN is a failure of the normal postnatal fall in pulmonary vascular resistance leading to ongoing right to left shunting across the fetal channels (PFO and PDA) and resultant hypoxia. In many babies with PPHN, the major shunting occurs at an intrapulmonary level.

PPHN is still one of the main causes of neonatal morbidity and mortality, with a mortality rate of 4–33%

PPHN is associated with multiple possible etiologies, usually accountable for its severe outcomes

All of the above

Identify the signs and symptoms associated with PPHN. Tick ALL that applies.

High Oxygenation Index (OI)

Persistent hypoxaemia and wide swings in arterial PO2

Hypoxaemia is out of proportion to the severity of parenchymal lung disease on CXR unresponsive to supplemental oxygen

Systemic hypotension

Severe cyanosis or desaturation unresponsive to supplemental oxygen

Low Oxygenation Index

Which of the following is the gold standard test for diagnosing PPHN?

Chest Xray

Echocardiography

Pulse Oximetry

Blood Tests

Identify the properties of inhaled Nitric Oxide (iNO) which makes it the ideal treatment modality for PPHN. Tick ALL three that applies.

Potent

Reductive

Selective

Vasodilator

What is the optimum starting dose of inhaled Nitric Oxide?

10 parts per million

20 parts per million

30 parts per million

40 parts per million

Extracorporeal Membrane Oxygenation (ECMO) is indicated for which of the following clinical conditions?

Severe respiratory failure

High inotrope requirement

Oxygen index >40
