Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
High-flow nasal cannula oxygenation group
High-flow nasal cannula oxygenation
The patients receive oxygen flow of 6L/min for preoxygenation with an high-flow canular oxygenation device before losing of conscious. Then, the oxygen flow is adjusted to 60L/min with the oxygen concentration of 100% and the temperature of 37℃ until the end of procedure.
Regular nasal cannula oxygenation group
Regular nasal cannula oxygenation
The patients receive an oxygen flow of 6L/min for preoxygenation with a disposal regular nasal cannula until the end of procedure.
