Table 1. Summary statistics for MVEase.

MVEase	Frequency (percentage) N=1399
0 = easy	752 (53.8)
1 = Oral airway used	523 (37.4)
2 = Two handed ventilation	118 (8.4)
3 = Extraglottic device required	6 (0.4)

* Mask ventilation was considered easy for MVEase classes 0 and 1 and difficult for MVEase classes 2 and 3. Local practice patterns often include placement of an oral airway for routine bag mask ventilation.
