“…1,15 The mean compression depth at the baseline rate of 100 min -1 was low in our sample, with half of our participants failing to meet the minimum 2005 recommended guideline depth of 38mm, suggesting better depth performance is required regardless of the rate.…”

“…1 In addition the new 2010 guidelines recommend an even greater depth of 50-60mm. 12 Our study showed an increase in the duty-cycle at faster rates approaching the recommended 50% at a compression rate of 160 min -1 .…”

“…1,2 However the quality of chest compressions is often poor during both training and actual resuscitation attempts. [3][4][5] Faster chest compression rates (120 vs. 60 min -1 ) improved immediate and 24 hour survival after ventricular fibrillation arrest in an animal study.…”

“…[19][20][21][22] Initial audit data showed a chest compression depth standard deviation of 13.67, such that a sample size of 40 patient participants per hospital site in each study period was required to detect a clinically important 10mm improvement in chest compression depth at 90% power and significance level of 0.05.

“…[3][4][5] The importance of quality CPR and the relevance of these parameters have been verified by researchers who have related the quality parameters to changes in rates of survival, return of spontaneous circulation (ROSC) or other clinical outcomes. The quality parameters give the researchers a valuable tool enabling success or failure to be related to specific compression techniques or other key elements of treatment.…”

EditorialChest compressions: The good, the bad and the ugly Trygve Eftestøl Where exactly is the chest compression, where does it begin, when does it end, how deep does it go and at what rate are they performed? In short -how good or bad is the chest compression? These are some of the questions researchers ask themselves repeatedly. As well as these data, we need to know the proportion of resuscitation time spent giving quality compressions, the ratio of interruptions and several other parameters and we need to evaluate the effect on survival. Considering the increasing capacity for data storage and growing repositories of resuscitation data one might also ask what proportion of valuable research time is spent in analysing compressions.In recent years there have been a growing number of research reports focussing on the quality of CPR. Studies based on data from resuscitation of cardiac arrest patients both in-and out-of-hospital provided evidence that resuscitation was not performed according to guidelines. In particular, interruptions in chest compressions and ventilations were found to be frequent during CPR. 1,2Since then, researchers have developed quantitative measures to characterise chest compressions, such as CPR fraction,
