- Data are presented as the mean ± SEM
- Spt, spontaneous breathing; 2/2, 2/2 breathing pattern; 4/4, 4/4 breathing pattern; SBP, systemic blood pressure; DBP, diastolic blood pressure; MBP, mean blood pressure; HR, heart rate; SV, stroke volume; CO, cardiac output
- * and ** p < 0.05 and p < 0.01, respectively, vs spontaneous breathing (paired t test). # and ## indicate p < 0.05 and p < 0.01, respectively, for comparison of the 4/4 breathing pattern and the 2/2 breathing pattern
