The aim of the study was to compare the intubation time and effectiveness, the grade of larynx visibility, and the ease of intubation in adults performed by nurses using 4 devices: a Macintosh blade laryngoscope (MAC), and a TruView EVO2 (EVO2), TruView EVO2 PCD (PCD), and ETView SL (ETView) laryngoscope, in simulated CPR settings with and without CC.
