Ambu AuraOnceDEVICE

Oropharyngeal leak pressure was determined by closing the expiratory valve of the anaesthesia breathing system and a fixed gas flow of 3 l minute-1. The airway pressure at which an equilibrium was reached was noted (maximum allowed 40 cm H2O).

Ambu AuraGainDEVICE

The airway tube view was scored using an established scoring system (4=only vocal cords visible; 3=vocal cords plus posterior epiglottis; 2=vocal cords plus anterior epiglottis; 1=vocal cords not seen)
