To deliver free flow oxygen, where should the flowmeter be set for a newborn?

To deliver free flow oxygen to a newborn, the flowmeter should be set to 10 liters per minute. This setting is optimal for providing sufficient oxygen concentration without risking oxygen toxicity or causing respiratory distress in neonates.

In neonatal care, the goal is to maintain an appropriate flow of oxygen to ensure that the infant receives enough oxygen to facilitate adequate oxygen saturation levels while avoiding excessive flow that could potentially lead to adverse effects like airway irritation or overdistension. A flow rate of 10 liters per minute strikes a good balance, offering enough oxygen to support neonatal physiology without overwhelming the delicate respiratory systems of newborns.

In contrast, higher flow rates can result in excessive turbulence and may not be necessary given the size and oxygen requirements of neonates. Hence, lower or higher rates are less effective or safe for this population.
