Intervention

Procedure:
• Tidal volume breathing technique
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 technique
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.
