100 participants were presented with a manikin and an airway management package containing a labelled i-gel and a mouthpiece with a filter which connected to the i-gel connector. They were given a sheet of instruction and attempted to ventilate the manikin. Time to ventilation, success rate, i-gel position and direction, and participant age and first aid experience were recorded. Participants rated their success and the ease of use, stated whether they would use the device in an emergency, and stated whether they would feel comfortable performing ventilation with the device. The three devices were generally comparable. However, the i-gel was quicker to insert, most likely due to the lack of inflatable cuff. The incidence and severity of both perioperative and postoperative complications was low.
