Question

Which of the following ventilator settings or respiratory measurements would be LEAST acceptable for a newborn with congenital diaphragmatic hernia (CDH)? Option 1: 100% FiO2 Option 2: PEEP of 20 cm H2O Option 3: Inhaled nitric oxide (NO) Option 4: PaCO2 of 55 mmHg Option 5: PaO2 of 65 mmHg

Answer 1

A PEEP of 20 cm H2O would be least acceptable in a newborn with Congenital Diaphragmatic Hernia (CDH) as a high PEEP can risk barotrauma and pneumothorax. Lower PEEP settings are typically preferred.

Step-by-step explanation:

In the context of Congenital Diaphragmatic Hernia (CDH), newborns often require ventilation treatment. However, the ventilator settings and respiratory measurements should be appropriately determined to provide optimal treatment. Among the options provided, a PEEP of 20 cm H2O would be least acceptable for a newborn with CDH. The Positive End-Expiratory Pressure (PEEP) sets the minimum pressure in the lungs at the end of an exhalation. However, a high PEEP can cause barotrauma, leading to pneumothorax, a serious lung condition. Therefore, a lower setting, generally lower than 5 cm H2O, is typically used in newborns, particularly newborns with CDH.
