Use of an intubating laryngeal mask airway on out-of-hospital cardiac arrest patients in a developing emergency medical service system.

Background/purpose: An intubating laryngeal mask airway (ILMA) is an alternative device for airway control, capable of providing effective ventilation in various situations. The purpose of this study is to compare the effects of the ILMA and bag-valve-mask (BVM) ventilation devices on out-of-hospital cardiac arrest (OHCA) patients.

Methods: An ILMA training course was conducted by emergency medical technicians (EMTs).
