Abstract

Purpose: The 2005 guidelines for cardiopulmonary resuscitation (CPR) caution that effective compression is essential (Class I) and chest compression (CC) by rescuers should be switched every 2 minutes to avoid rescuer's fatigue. It is controversial how long effective CC by a single individual can be provided. There are few reports about CPR quality, especially when rescuers perform CC for more than 10 minutes. The mean CPR period was about 30 minutes in Korea. We investigated the quality of CC and rescuer s fatigue after about 30 minutes. Methods: From April 2009 to July 2009, health care providers (HCPs) were recruited into this study. The study simulated 2 person, in-hospital CPR. On the test day, which had been randomly assigned, each participant performed 7 CCs for about 30 minutes. The period of each CC was 2 minutes, and the period of each circulation check was 5 seconds. Participants' heart rates (HR) and visual analogue scale (VAS) scores for fatigue were obtained before and after each CC. Data for each 2 minutes CC was obtained with the use of Resusci $Anne^{(R)}$ with the $Laerdal^{(R)}$ PC skill reporting system. We used one-way repeated measures ANOVA for comparison of quality and fatigue of each CC and multiple linear regression for finding the predictors for correct CC. SPSS 17.0 was used for analysis. Results: Among a total of 30 HCPs, data from 27 were analyzed. All participants were certified as a BLS provider and some were certified as BLS instructors. The rate of effective compression was $83.8{\pm}24.3%$. Despite 2 min CC tasks were repeated alternatively for about 30 minutes, there were no differences in the number of correct CCs, depth and velocity of compression, and the number of incorrect CCs. Conclusion: During in-hospital CPR, HCPs may provide effective chest compressions on shifts with minimal effect of fatigue, even if they provide CC for 30 minutes.
