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 QI (%) 21 (20) .52(−.07–.78) 13.83 38.33 101%
Depth QI (%) 12 (9) .81(.54–.91) 3.38 9.33 21%
Leaning QI (%) 15 (13) .77(.36–.90) 6.30 17.47 42%
Duty cycle QI (%) 10 (11) .68(.29–.85) 6.25 17.33 96%
