The study was carried out using a patient manikin (Resusci Anne Advanced SkillTrainer®, Laerdal Medical, Norway). These simulators are regularly used at our clinic for basic life support training and all participants have trained with this simulator before, but did not intubate this manikin before. There was no additional artificial aggravation of the airway anatomy. The manikin was placed dorsally on a standard table, while the chest compressions were performed using a mechanical resuscitation device during intubation (Corpuls CPR®, GS Elektromedizinische Geräte, Germany). In order to simulate more realistic movement of the torso during intubation, the manikin was elastically supported. The process of the intubation was documented by video recording. Participants were instructed to perform tracheal intubation with ongoing chest compressions. In the event of failed intubation, a new attempt had to be made.
