PURPOSE: Chest compressions are often performed at a variable rate during cardiopulmonary resuscitation (CPR). The effect of compression rate on other chest compression quality variables (compression depth, duty-cycle, leaning, performance decay over time) is unknown. This randomised controlled cross-over manikin study examined the effect of different compression rates on the other chest compression quality variables. METHODS: Twenty healthcare professionals performed 2min of continuous compressions on an instrumented manikin at rates of 80, 100, 120, 140 and 160min(-1) in a random order. An electronic metronome was used to guide compression rate. Compression data were analysed by repeated measures ANOVA and are presented as mean (SD). Non-parametric data was analysed by Friedman test. RESULTS: At faster compression rates there were significant improvements in the number of compressions delivered (160(2) at 80min(-1) vs. 312(13) compressions at 160min(-1), P
