Manual versus Automated Ventilation with an i-gel ^® Airway During Short-Haul Helicopter Operations

OBJECTIVES: airway. METHODS: movement was documented and each stretcher attendant completed a post-simulation operational usability survey. Paired comparisons between manual and automated ventilation were analyzed using McNemar's exact test for the primary outcome and Wilcoxon signed-rank tests for secondary outcomes. RESULTS: movement and resulted in four ventilation disconnects (two static, two live) while no disconnects were observed during automated ventilation; participants also reported greater preference for automated ventilation. CONCLUSIONS: airway.
