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

Table 2

Comparison of cardiopulmonary resuscitation quality parameters between the two groups.

Parameter	1-minute group	2-minute group	value
Chest compression rate (per min)	116.1 ± 12.5	117.8 ± 12.4	0.077
Chest compression depth (mm)	45.8 ± 7.2	44.5 ± 7.1	0.010
Adequate compression depth (%)	21.5 (7.3, 51.8)	19.5 (2.0, 42.3)	0.004
Adequate compression rate (%)	36.0 (20.5, 74.5)	51.5 (28.0, 83.8)	0.163
Interruption time (seconds)	28.0 (18.0, 56.8)	13 (9.0, 56.8)	0.001
Correct hand position (%)	100 (85.0, 100)	100 (76.0, 100)	0.509
Full-chest recoil (%)	53.9 ± 29.6	51.1 ± 31.2	0.162
