Summary

One-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver are three common airway management maneuvers. Sniffing position may improve ventilation between these three maneuvers. The investigators hypothesize that ventilation efficiency may be different between these three maneuvers whether the patient is in sniffing position or neutral position. The investigators would like to quantify this effect by measuring the expired tidal volume, airway pressure, EtCO2 slope and hemodynamic change between these three maneuvers during anesthesia induction.

Detailed description

Mask ventilation is considered a important skill for airway management during general anesthesia induction and for apneic unconscious patients. One-handed E-C clamp mask holding technique, two-handed mask ventilation with jaw thrust, and two-handed mask ventilation with triple airway maneuver are three common airway management maneuvers. However, the efficiency of ventilation between these three maneuvers has to be clarified. Besides, whether sniffing position or neutral position may improve ventilation between these three maneuvers is to be determined. The investigators will collect airway parameters of the patients receiving general anesthesia and measure the expired tidal volume, airway pressure, EtCO2 slope and hemodynamic change between these three maneuvers during anesthesia induction.

Interventions

Type	Name	Description
PROCEDURE	airway maneuver	Three-period crossover study: During general anesthesia induction, subjects are assigned to one of the 6 airway maneuver sequences (ABC, CAB, BCA, ACB, CBA, or BAC) in accordance with a randomization schedule. Each maneuver is performed 5 times in a period. Airway maneuver A: E-C clamp mask holding technique; Airway maneuver B: two-handed mask ventilation with jaw thrust airway maneuver; Airway maneuver C: two-handed mask ventilation with triple airway maneuver(combine jaw thrust and head tilt chin lift)
