| Label | Type | Description | Intervention Names |
|---|---|---|---|
| High-flow nasal oxygen technique | Experimental | 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. |
|
| Mask ventilation technique | Active Comparator | 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. |
