The aim of the study is to assess whether perioperative use of high-flow nasal oxygen (HFNO) during the period from induction of anesthesia until discharge from the post-anesthesia care unit in patients undergoing robotic-assisted surgery reduces perioperative oxygen desaturation and postoperative pulmonary complications.
Age >= 18
Undergoing non-emergent, non-cardiac, intra-abdominal, intra-thoracic or pelvic robot-assisted surgery with an expected duration of at least 2 hours under general anesthesia with planned extubation at the end of the procedure
Known pregnancy
Preoperative intubation or tracheostomy
Anatomical or clinical conditions precluding the use of high-flow nasal oxygen (severe midface trauma, recent nasal surgery, severe nasal septum deviation, severe nasal deformation)
Contraindications to electrical impedance tomography (EIT), including inability to place the EIT belt or presence of active implantable electronic devices (e.g., pacemaker or implantable cardioverter-defibrillator)
