What is the maximum volume of air that should be delivered during positive pressure ventilation in a newborn?

The correct answer indicates that the maximum volume of air that should be delivered during positive pressure ventilation in a newborn is 20-30 ml. This volume is based on the physiological needs of newborns, who have smaller lung capacities compared to older children and adults. Delivering an appropriate volume is crucial to ensure effective ventilation without risking over-inflation of the lungs, which can lead to complications such as pneumothorax or barotrauma.

Maintaining appropriate ventilation volumes during resuscitation is key to delivering adequate oxygen while preventing injury. The specified range of 20-30 ml is designed to optimize respiratory efforts during critical care situations, reflecting careful consideration of the newborn’s size and respiratory mechanics. Thus, adhering to this volume ensures effective and safe ventilatory support in newborns.
