The purpose of this study was to comparative analysis of tidal volume and airway pressure after one-rescuer BVM, two-rescuer BVM, advanced airway devices with a Bag-valve mask using RespiTrainer. The data were obtained from June 2 to 10 in 2014. The collected data were analyzed using the SPSS WIN 18.0 program. The results showed that BVM ventilation using the endotracheal intubation produced higher mean tidal volume 497 ± 78 mL, Two-rescuer ventilation 479 ± 91 mL One-rescuer ventilation 386 ± 59 mL, King LTS-D 365 ± 05 mL, Laryngeal mask airway (LMA) 351 ± 35 mL. Peak airway pressure was higher in BVM ventilation using the endotracheal intubation. As a result, the study confirmed that the BVM Ventilation by endotracheal intubation and Two-rescuer BVM ventilation to one third the bag depth squeeze method is appropriate.
