ResumoIntroduction: Aim of this study was to compare the effect of a 40:2, 15:2 versus 30:2 Compression: Ventilation (C:V) ratio on rate of Chest Compression (CC), rescuer fatigue and satisfaction.We measured the BP and pulse.Material and Methods: 53 persons performed BLS and CPR using C: V of 15:2, 30:2, 40:2 on a adult resuscitation lardal manikin for two minutes.Two researcher measured the above mentioned variables.Data were analyzed by ANOVA, student's t-test or Mann-Whitney U test between groups.The value of P<0.05 was considered as significant.The results revealed fatigue after 2 minutes and satisfaction from the performed technique in the groups differed (p<0.05).Results: Number of breathing in two minutes was 8.8±4.7 (1-24).Total cardiac massage in two minutes in the study groups was 131.7±40.6 (20-265), of this number in 130.6±40.5 was done correctly.The number of compression per two minutes increased with C: V ratio of 40:2 than to other C: V ratio.Most of participants (71.7%) prefer using 30:2 ratio to achieve the primary goal of Cardiopulmonary Resuscitation (CPR).PR and systolic, diastolic BP of rescuers before and two minutes after resuscitation had insignificant difference (P<0.001), and SBP differed between groups (P<0.04).Conclusion: Although the rescuers prefer to perform the C: V ratio 30:2, but number of CC is less than standard recommended by AHA.Alternative C: V ratio of 40:2 methods, is equal to the AHA recommended 80 compressions/minute, and also highest number of CC is done in 2 minutes, While, in the other methods is less than the recommended number.
