Comparison of Two Nasal Interface for CPAP in Preterm

Continuous distending airway pressure (CPAP) has gained popularity as a means to provide non-invasive respiratory support in neonates to reduce ventilator induced lung injury (VILI). However, maintaining CPAP in preterm infants has been challenging, often related to issues with nasal interface such as nasal septal injury, problems with keeping the prongs in the nose and leak around the prongs with are important factors in proving effective CPAP. RAM cannula was recently approved for providing supplemental oxygen and soon adapted by many centers to provide CPAP in preterm infants. Concerns have been raised that RAM cannula interface results in sub-optimal pressure delivery compared to standard nasal prongs.
