Ventilator setting and PaO2/FiO2 before developing pneumothorax
| Ventilatory setting in intubated patients before developing pneumothorax TV (median IQR) Plateau pressure (mean±SD) PEEP (median IQR) Driving pressure (mean±SD) | 400 (358–420) mL 26.4 (±4.27) cm H2O 8 (6–10) cm H2O 17.3 (±5.19) cm H2O |
| Length NIV before developing pneumothorax (median IQR) | 1 (1–2) day |
| Length of IV before developing pneumothorax (median IQR) | 9 (4–21) days |
| PaO2/FiO2 ratio on admission (median IQR) | 81 (67.5–130) |
| PaO2/FiO2 before pneumothorax (median IQR) | 122 (84–179) |
NIV, non-invasive ventilation; PaO2/FIO2, pressure of arterial oxygen to fractional inspired oxygen concentration; PEEP, positive end-expiratory pressure; TV, tidal volume.
