Premature Newborns Treated With Less Invasive Surfactant Administration Under Heated Humidified High-flow

Nasal Continuous Airway Pressure (CPAP) or Heated humidified high-flow Air support with nasal cannula (HHHFNC) are among the most commonly used non-invasive respiratory support methods. The purpose of this prospective study was to compare vital findings, blood gas parameters, perfusion index (PI) and plethysmographic variability index (PVI) values in premature infants treated with less invasive surfactant administration (LISA) under HHHFNC or CPAP.
