CPR Compression Rotation Every One Minute Versus Two Minutes: A Randomized Cross-Over Manikin Study

Table 3

Comparison of rescuer’s fatigability parameters (heart rate, respiratory rate, and fatigue) at baseline and at the end of each rotation between the two groups.

Parameter	1-minute group	2-minute group	value
Heart rate (beats/min)
Baseline; Final	84.36 ± 12.03; 109.36 ± 17.29	85.30 ± 11.49; 111.19 ± 18.02	0.360; 0.218
Change	25.00 ± 15.43	25.9 ± 15.42	0.596
Respiratory rate (breaths/min)
Baseline; Final	17.73 ± 2.65; 23.85 ± 4.48	17.40 ± 2.32; 25.32 ± 4.20	0.122; < 0.001
Change	6.13 ± 4.71	7.91 ± 4.40	<0.001
Fatigue (VAS score)
Baseline	1.03 ± 0.17	1.07 ± 0.25	0.071
Final	4.96 ± 1.76	5.66 ± 1.64	<0.001
Change	3.93 ± 1.78	4.60 ± 1.66	<0.001
