Trends in chest compression performance over time. Circles and bars represent means and standard deviations, respectively. Residual leaning rate is the ratio of the number of compressions with residual leaning to the total number of compressions; residual leaning is defined as ≥2.5 kg residual force on the chest at the end of the release phase of each compression.
