Fig. 2From: The influence of different patient positions during rapid induction with severe regurgitation on the volume of aspirate and time to intubation: a prospective randomised manikin simulation studyThe three positions of the manikin used: (a) Reverse Trendelenburg position (+ 15°) and head supported by a pillow (‘sniffing position’); (b) Trendelenburg position (− 15°) and ‘sniffing position’; (c) Trendelenburg position (− 15°) and full cervical spine extension (‘Sellick’). Sellick position was determined by tilting the head rest until the head started to suspend in mid-airBack to article page
