The Effect of a Mechanical Compression Device and Supraglottic Airway on Flow Time: A Simulation Study of Out-of-Hospital Cardiac Arrest in a High-Rise Building

Figure 2

Cumulative flow time fraction in each phase. Phase 1: from initiating CPR at the scene until performing CPR according to 1 of the 4 scenarios, Phase 2: from leaving the scene until entering the elevator, Phase 3: from entering the elevator until exiting it, Phase 4: from exiting the elevator until loading the manikin into an ambulance, MAB: manual compression with bag-valve mask, MAS: manual compression with supraglottic airway, MEB: mechanical compression with bag-valve mask, MES: mechanical compression with supraglottic airway. †, ‡, § significant between group differences demonstrated in the post hoc analysis.
