Conditions

Adult Patients 20 Years of Age or Older Who Are Planning to Undergo Surgery Under General Anesthesia

Interventions

High-flow nasal oxygen techniquePROCEDURE

High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system during anesthetic induction. Pulse oximetry and oxygen reserve index will be monitored continuously.

Mask ventilation techniquePROCEDURE

Oxygen will be supplied through the mouth and nose to the patients using facial mask during anesthetic induction. Pulse oximetry and oxygen reserve index will be monitored continuously.
