Applied tidal volumes dependent on the supraglottic device. No significant differences in the application of "sufficient" tidal volumes (> 500 ml) were found among the 4 devices (p = 0.08). Analysis of subgroups with tidal volumes of 500-800 ml and > 800 ml found significantly smaller but sufficient tidal volumes (500-800 ml) in LMA* ventilated patients (p < 0.0001). Data are presented in numbers.
