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)	V_t (ml/kg)	V_min (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
SB-group (N = 5)	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
MV-group (N = 5)	T3	89 ± 1	90 ± 0	5.8 ± 0.3	524 ± 24	31.2 ± 5.0	20.9 ± 3.7

EELV, V_min, V_t, 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
