Comparison of Chest Compression Quality Using Wing Boards versus Walking Next to a Moving Stretcher: A Randomized Crossover Simulation Study.

Background: When a rescuer walks alongside a stretcher and compresses the patient's chest, the rescuer produces low-quality chest compressions. We hypothesized that a stretcher equipped with wing boards allows for better chest compressions than the conventional method.

Methods: In this prospective, randomized, crossover study, we enrolled 45 medical workers and students.
