Which of the following statements are true Concerning the use of extraCorporeal membrane oxygenation (ECMO) for patients with Congenital diaphragmatic hernia
I.The higher oxygenation index, the worse a patient's ability to oxygenate, despite high levels of ventilatory support.
II.A low numerator when calculating oxygen index means high oxygen support.
III.A low denominator when calculating oxygen index means poor tissue oxygenation.
IV.Inhaled nitric oxide and ECMO are frequently used.

Question

Quizplus · Accepted Answer

I, III, and IV are true. The oxygenation index is a measure of the severity of hypoxemic respiratory failure and is calculated as (FiO2 * mean airway pressure * 100) / PaO2. A higher oxygenation index indicates worse oxygenation despite high levels of ventilatory support, not the other way around. A low denominator (PaO2) in the oxygen index calculation indeed means poor tissue oxygenation. Inhaled nitric oxide and ECMO are frequently used in the management of congenital diaphragmatic hernia to improve oxygenation and reduce pulmonary hypertension.
