Arm && Interventions

Group	Intervention	Description
Tidal volume breathing technique	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	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.

Primary Outcome Measures

Name	Time	Method
Oxygen reserve index	for 10 minutes before anesthetic induction. At Day 0.	End-tidal O2 will be monitored continuously before anesthetic induction.
