About this trial
The study investigates the influence of three types of ventilation mode by using Bi-Level positive airway pressure (pinsp 20 mbar, PEEP 5, AF 10/min) with two different types of ventilators ( Medumat vs. MeduVENT ), Continuous positive airway pressure (PEEP 5, AF 10/min, ASB 10) and Chest Compression Synchronized Ventilation (pInsp = 30 vs. 60 mbar; respiratory rate = chest compression rate, PEEP 5) with regard to achieving a sufficient tidal volume and the tightness of various supraglottic airway devices (laryngeal mask, i-Gel-laryngeal mask, laryngeal tube) and endotracheal intubation.
