- Data are presented as the mean ± SEM
- Spt, spontaneous breathing; 2/2, 2/2 breathing pattern; 4/4, 4/4 breathing pattern; Syn, synchronization time; RSA, HR Max minus HR Min; BR, breath rate
- ** and *** p < 0.01 and p < 0.001, respectively, vs the spontaneous breathing pattern (paired t test). ### p < 0.001, respectively, for a comparison of the = 4/4 breathing pattern and the 2/2 breathing pattern
