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 ability of oxygenation with high-flow nasal oxygen therapy and mask ventilation technique for induction of anesthesia in adult patients who are planning to undergo surgery under general anesthesia.
Interventions
PROCEDUREHigh-flow nasal oxygen technique
High-flow nasal oxygen will be applied to the patients through nasal openings using Optiflow system during anesthetic induction. Pulse oximetry and oxygen reserve index will be monitored continuously.
PROCEDUREMask ventilation technique
Oxygen will be supplied through the mouth and nose to the patients using facial mask during anesthetic induction. Pulse oximetry and oxygen reserve index will be monitored continuously.
