Comparing Bubble and Ventilator Nasal CPAP in Preterm Infants

There are various methods to generate the pressure needed for Nasal CPAP. Some neonatal intensive care units (NICU) use an underwater bubbling system and others use a ventilator to generate the pressure. There is no right or wrong way to generate the pressure and both methods are approved and accepted. The aim of this study is to compare the two systems of Nasal CPAP by placing the baby on each for a defined time period and reviewing the infant's vital signs. The investigators expect that the pressure generated by bubble CPAP will be better and lead to improved vital signs.
