Enrollment

Conditions

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

Interventions

Tidal volume breathing techniquePROCEDURE

High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system before anesthetic induction. Tidal volume breathing will be applied. Pulse oximetry, end-tidal O2, and oxygen reserve index will be monitored continuously.

Vital capacity breathing techniquePROCEDURE

High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system before anesthetic induction. Vital capacity breathing will be applied. Pulse oximetry, end-tidal O2, and oxygen reserve index will be monitored continuously.
