58 participants in 2 patient groups

Tidal volume breathing technique

Experimental group

Description:

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.

Treatment:

Procedure: Tidal volume breathing technique

Vital capacity breathing technique

Active Comparator group

Description:

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.

Treatment:

Procedure: Vital capacity breathing technique
