HFNC vs continuous positive airway pressure (CPAP)

Adverse events ‐ abdominal overdistention · respiratory support in term infants (infants ≥ 37 weeks gestational age to the end of the neonatal period (up to 1 month postnatal age))

HFNC vs low flow nasal cannula (LFNC)

Treatment failure · respiratory support in term infants (infants ≥ 37 weeks gestational age to the end of the neonatal period (up to 1 month postnatal age))

Summary of findings table ‐ High flow nasal cannula (HFNC) may leads to lower treatment failure compared with low flow nasal cannula (LFNC) (low certainty).
