The flow rate of Bubble CPAP is 5-10 L/min. All children with severe pneumonia and many neonates with RDS require supplemental oxygen. It helps keep the infant's airways open and increase the amount of oxygen in their lungs. This machine used a nasal cannula or a mask attached to the newborn's nose, connected to the infant bubble CPAP machine, which delivers a continuous flow of air or oxygen at a specified pressure.
