Airway Morbidity Clinical Trial
Official title:
Comparative Evaluation of One-handed E-C Clamp Mask Holding Technique, Two-handed Mask Ventilation With Jaw Thrust, and Two-handed Mask Ventilation With Triple Airway Maneuver in the Unconscious Apneic Person

Study type | Interventional |
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.
