AbstractAbstract PDF
Background
:Newly revised cardiopulmonary resuscitation (CPR) guideline in 2005 recommends 30 chest compressions and 2 rescue breaths during CPR for all rescuers to use for all adult victims. We would compare the accuracy of the CPR methods by revised CPR guideline in 2005 and previous guideline in 2000. Materials and Methods:Fifty medical students during the introduction to clinical medicine (ICM) were investigated after 30 minutes lecture and brief education of CPR methods. Each students performed twice both CPR methods, the one by guideline 2005 (method A), 4 cycles of 30 compressions every 2 breaths, and the other by guideline 2000 (method B), 10 cycles of 15 compressions every 2 breaths. Resci® Anne mannekin and Laerdal® skillmeter were used and paper reports were printed after each tests. After then, we compared the technical accuracy of the results between method A (30:2) and method B (15:2).
Results
:Total fifty students (37 males, 13 females) were tested, their mean age was 25.1, mean body weight was 63.5 kg. The technical accuracy on chest compression was not different between two methods and also the technical accuracy on ventilation was not different between two methods except total ventilation number (p>0.05).
Conclusion
:We could not find significant differences of technical accuracy between both CPR methods. So we don’t think new guideline 2005 is superior to previous guideline 2000 by technical efforts although it’s hemodynamic responses and other clinical benefits is excluded in this study.
