Physiologic data for the experimental groups at the beginning and at the end of the ventilation stage, either for SB-group or MV-group
| Group | Time | SpO2 (%) | RR (1/min) | Vt (ml/kg) | Vmin (ml/min*kg) | EELV (ml/kg) | Global strain (%) |
|---|---|---|---|---|---|---|---|
| SB-group (N = 5) | T1 | 87 ± 1 | 117 ± 10 | 5.4 ± 0.9 | 636 ± 129 | 26.2 ± 2.5 | 22.6 ± 5.6 |
| T3 | 91 ± 2 | 129 ± 13 | 6.8 ± 1.4 | 892 ± 224 | 21.5 ± 0.7 | 32.4 ± 7.2 | |
| MV-group (N = 5) | T1 | 92 ± 2 | 90 ± 0 | 5.6 ± 0.3 | 508 ± 23 | 33.2 ± 3.8 | 17.8 ± 1.9 |
| T3 | 89 ± 1 | 90 ± 0 | 5.8 ± 0.3 | 524 ± 24 | 31.2 ± 5.0 | 20.9 ± 3.7 |
EELV, Vmin, Vt, and global strain were obtained from image analysis of μ-CT images
No significant changes were detected between T1 to T3 in any of the groups
