Multicenter Study Comparative Study Clinical Trial
Comparison of arterial blood gases of laryngeal mask airway and bag-valve-mask ventilation in out-of-hospital cardiac arrests.
Focusing on the efficacy of successful ventilation during cardiopulmonary resuscitation (CPR) with alternative airways, previous reports investigated various parameters such as success rate, tidal volume, incidence of regurgitation, etc. However, there are few investigations of arterial blood gases (ABG) during CPR with alternative airways, especially the laryngeal mask airway (LMA). ⋯ LMA does not greatly benefit the respiratory status of patients such as in this study population. Delayed placement of a LMA will be recommended to achieve minimally interrupted chest compression in an out-of-hospital CPR protocol for witnessed VF cases following shock.
