64 participants in 2 patient groups

HFNC

Experimental group

Description:

HFNC with a 60 liters per minute flow will be given to the patients before anesthesia induction and before extubation at the end of the surgery

Treatment:

Procedure: HFNC group

Standard

Active Comparator group

Description:

This patients will be managed as usual care. Pre-oxygenation before induction will be performed with supplemental oxygen but without positive pressure. After extubation patients will be oxygenated through a ventury mask.
