Figure 1 The airway model consisted of a pharyngeal
modelTM attached to measuring scales.

were provided to participants.

Figure 5 Boxplot graph illustrating cricoid pressure force (N,
mean) with 95% confidence intervals, applied at baseline (blue) and
post-teaching (red) on “awake” and “anaesthetised” patients. Target
ranges are shaded green.
