Nasal Cannula are mostly employed to give extra oxygen. The use of NC for NCPAP was advised against due to the unregulated pressure. Next, in preterm babies already receiving NCPAP for AOP, Compared the use of Nasal Cannula at flows of up to 2.5 L/min with NCPAP produced by a ventilator utilising Argyle prongs (Covidien, Minneapolis, Minnesota, USA). All of the babies in this crossover research began off on NCPAP.
The infants were switched to Nasal Cannula for additional six hours after the initial six. By monitoring esophageal pressures, the authors evaluated delivered airway pressure. Sreenan's team discovered that the NC could provide a similar constant displacing pressure. The weight of the newborn affected the quantity of flow needed to produce similar pressures. The incidence and length of apnea, bradycardia, or desaturation events were same between the two systems. With nonhumidified Nasal Cannula, flow rates typically range from 0.5 to 2 L/min. Low-flow NC may have a drying impact on nasal secretions due to the nonhumidified nature of the gases utilised, which might induce blockage or localised bleeding.
