Table 2 Mean absolute difference chest compression and between-day reliability – Time point 1 and Time point 2

From: Consistency and variability in human performance during simulate infant CPR: a reliability study

  Mean (SD) absolute difference ICC (95% CI) SEM MDC MDC as % of mean (time point 1)
Rate (cpm) 9.0 (7.0) .86 (.69–.94) 2.63 7.28 7%
Depth (mm) 1.9 (1.6) .92 (.68–.97) 0.44 1.23 3%
Leaning (kg) 0.6 (0.5) .78 (.42–.91) 0.23 0.65 22%
Duty cycle (%) 5.7 (6.7) .75 (.44–.89) 3.38 9.36 21%
  1. cpm Compressions per minute, SD Standard deviation, ICC Intraclass correlation coefficient, SEM Standard error of measurement, MDC Minimal detectable change
