Nasal High Frequency in Preterm Neonates

"Preterm neonates who will be allocated will start nHFOV: (CNO, Medin, Germany). nHFOV will be provided via binasal prongs (Size: small, medium, large; Diameter according to its chart; Medin, Germany).~The initial parameters will be mean airway pressure (MAP) of 6 cm H2O (range 6-10), frequency of 8 Hz (range 8-12) and amplitude will be adjusted until infant's chest showed slight oscillations and amplitude will be 7 (range 7-10).~The fraction of inspired oxygen (FiO2) will be adjusted to maintain target oxygen saturation (SpO2) from 92% to 95% by a pulse oximeter."

Preterm neonates who will be allocated to this group to the nCPAP will be started on a pressure of 6-8 cm H2O, FiO2) will be adjusted to maintain target oxygen saturation (SpO2) from 92% to 95% by a pulse oximeter
