Measurements of lung mechanics at different PEEP levels
| ZEEP | 50 % iPEEP | 80 % iPEEP | 100 % iPEEP | 150 % iPEEP | |
|---|---|---|---|---|---|
| Set PEEP (cmH2O) | 0 | 5 | 8 | 10 | 15 |
| PEEP tot measured (cmH2O) | 10 | 10 | 11 | 11 | 15 |
| Plateau pressure (cmH2O) | 18 | 21 | 20 | 19 | 21 |
| Expired tidal volume (ml) | 505 | 515 | 515 | 500 | 372 |
| Static compliance (ml/cmH2O) | 63 | 47 | 57 | 62.5 | 62 |
| Trapped volume (ml) | 390 | 350 | 150 | 80 | 0 |
ZEEP zero end-expiratory pressure, iPEEP intrinsic positive end-expiratory pressure, PEEP positive end-expiratory pressure
