Comparative evaluation of high-flow nasal cannula oxygenation vs nasal intermittent ventilation in postoperative paediatric patients operated for acyanotic congenital cardiac defects

Postcardiopulmonary bypass respiratory complications in paediatric patients with congenital acyanotic heart disease can be minimised with newer oxygen therapy devices such as AIRVO (HFNC) or RAM cannula (NIV). In comparison between these two, AIRVO did not show improved CO washout over RAM cannula; however, it did provide better oxygenation as measured by pO in arterial blood and pO/FiO ratio immediate postextubation. Also, long-term results such as duration of mechanical ventilation and ICU stay were not affected by the choice of device.
