The mean compression rate was within guidelines in just under half (48 %, <em>n</em> = 24) of all participants. Only 20 (40 %) participants exposed the manikin's chest. Only 46 % (<em>n</em> = 23) of participants felt that the overall descriptions offered during the tCPR guidance were understandable, while 80 % (<em>n</em> = 40) and 36 % (<em>n</em> = 18) felt that the instructions on hand placement and compression rate were understandable, respectively. Lastly, 94 % (<em>n</em> = 47) of participants agreed that they would be more likely to perform bystander CPR if they were provided with tCPR.</p></div><div><h3>Conclusion</h3><p>The quality of CPR performed by laypersons is generally suboptimal and this may affect patient outcomes. There is an urgent need to develop more understandable tCPR algorithms that may encourage bystanders to start CPR and optimise its quality.</p></div>","PeriodicalId":48515,"journal":{"name":"African Journal of Emergency Medicine","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10542001/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41155215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
