Table 1 Physiologic data for the experimental groups at the beginning and at the end of the ventilation stage, either for SB-group or MV-group

From: Progression of regional lung strain and heterogeneity in lung injury: assessing the evolution under spontaneous breathing and mechanical ventilation

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
  1. EELV, Vmin, Vt, and global strain were obtained from image analysis of μ-CT images
  2. No significant changes were detected between T1 to T3 in any of the groups
