What is the most common device used for positive pressure ventilation in newborns in the prehospital setting?

The self-inflating bag-mask device is the most common tool used for positive pressure ventilation in newborns within the prehospital environment because of its practicality and ease of use. This device can deliver air or oxygen to the infant's lungs effectively, making it crucial in situations where immediate ventilation is necessary, such as in cases of respiratory distress or apneic episodes.

Self-inflating bags are designed to automatically refill after the rescuer releases the bag, allowing for continuous and immediate access to positive pressure ventilation without the need for a constant gas source. This feature is particularly valuable in emergency settings where quick action is critical and where resources may be limited. Additionally, the device typically comes with a mask that can adapt to the newborn’s small facial structures, ensuring a good seal.

In the context of prehospital care for newborns, the self-inflating bag is user-friendly, allowing healthcare providers to focus on delivering care without complex operational requirements. This simplicity, combined with efficiency in ventilation delivery, makes it the preferred choice in emergency situations involving newborns.
