a
Calculation was made in mechanically ventilated patients (n = 354).
MV: invasive mechanical ventilation; NIV: non-invasive mechanical ventilation; PEEP: positive end-expiratory pressure; PIP: peak inspiratory pressure; PNMD: pneumomediastinum; SD: standard deviation: TSS: overall lung total severity score; TV: tidal volume.
