This week CanadiEM is featuring an article from the Canadian Journal of Emergency Medicine (CJEM) that focuses on the most basic of skills: CPR. We know that CPR delivered by bystanders can increase the rate of survival from out-of-hospital cardiac arrest (OHCA), but all too often it is not done. In fact, it is performed <30% of the time in the Canadian context.
Featured in the latest CanadiEM infographic, this study by Cheskes et al [cite num=”1″] set out to determine whether Canadians are more willing to perform chest-compression-only CPR than traditional CPR, describe the public’s knowledge of OHCA, and identify factors that lead bystanders to perform CPR (or not!). The methodology involved a 32-item survey disseminated across Canada to 428 participants. Survey says: a significnatly greater proportion of respondents were up for chest-compression-only CPR compared to traditional CPR. This survey-based finding has been borne out in at least one recent registry study [cite num=”2″].
This study suggests that the general public has an aversion to traditional mouth-to-mouth CPR strong enough that it may prevent them from performing CPR, especially in certain populations. Previous randomized controlled trials have shown no difference in outcomes [cite num=”3,4,5″] although two meta-analyses of these three trials showed a benefit of chest-compression-only CPR over traditional CPR [cite num=”6,7″]. Observational studies have had conflicting results [cite num=”8,9″]. This study supports chest-compression-only CPR training for the general public and the endorsement of this practice by the Canadian Red Cross and American Heart Association. It can be read on the CJEM website [cite num=”1″] with key results reviewed in the infographic above.
