Adult Patients 20 Years of Age or Older Who Are Planning to Undergo Surgery Under General Anesthesia
Conditions
Brief summary
The purpose of this study is to compare the preoxygenation efficacy of tidal volume breathing and vital capacity breathing.
Interventions
PROCEDURETidal 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.
PROCEDUREVital 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.
