| Electrical impedance tomography-derived regional compliance | Early prone position | Late prone position | P values | ||||
|---|---|---|---|---|---|---|---|
| PEEP/FIO2 table (n = 13) | Pes-guided strategy (n = 10) | PEEP/FIO2 table (n = 13) | Pes-guided strategy (n = 10) | Position effect | PEEP strategy effect | Position and PEEP interaction | |
| Sternal lung regions (mL/cmH2O) | 11 ± 4 | 13 ± 6 | 13 ± 6 | 15 ± 8 | 0.002 | 0.42 | 0.89 |
| Spinal lung regions (mL/cmH2O) | 22 ± 9 | 24 ± 9 | 21 ± 9 | 24 ± 12 | 0.99 | 0.57 | 0.51 |
Values are mean ± SD
