Fig. 2

The violin plots show the frequency density of the five last interventions recorded during the sedation. In the event of inadequate alveolar ventilation during sedation, the investigators sequentially implemented five interventions until all respiratory-related parameters returned to normal. The five interventions are represented in alphabetical order(a-e): a: increasing oxygen flow (5 L/min), b: a chin lift or jaw thrust maneuvre, c: placement of the nasopharyngeal airway and chin lift, d: mask positive-pressure ventilation, and e: ventilator-assisted ventilation with tube insertion
