The treatment of cardiac arrest in an extra-hospital environment improves with the increase in the number of people able to establish an early Cardio-Pulmonary Reanimation (CPR). The main aim of the study was to assess the validity of the two-step method in case of prolonged CPR.
A randomized comparison study was conducted in the University Nursing School of a Northern Italian town, during the 2015/16 academic year, among 60 students, to teach them CPR techniques, through two different teaching methods (4-step and the 2-step of CPR training). The effectiveness of the maneuvers performed on mannequins equipped with skill-meter was verified.
Our study did not highlight any significant difference between the two methods of CPR training. The comparison between the two methods regarding their efficacy in practical teaching of CPR, highlighted by this study, proved the validity of both the 4-minute continuous method (1st method) and the 30:2 method (2nd method).
The results of the study showed no differences between the 2-step and the 4-step methods, in the effectiveness of cardiac massage. The correct execution of chest compressions during a CPR is the key to increase the patient's chances of rescue. Research has shown that any interruption in the execution of chest compressions, leads to a progressive reduction of the effectiveness of cardiac massage, with negative consequences on the prognosis of the patient undergoing at CPR.
院外心脏骤停的治疗效果会随着能够实施早期心肺复苏（CPR）的人员数量增加而改善。本研究的主要目的是评估在长时间心肺复苏情况下两步法的有效性。
在2015/16学年，于意大利北部一个城镇的大学护理学院对60名学生进行了一项随机对照研究，通过两种不同的教学方法（4步法和CPR训练的2步法）教授他们CPR技术。对在配备技能测量仪的人体模型上进行的操作效果进行了验证。
我们的研究未发现两种CPR训练方法之间存在任何显著差异。本研究突出的两种方法在CPR实践教学效果方面的比较，证明了4分钟连续法（第一种方法）和30:2法（第二种方法）的有效性。
研究结果表明，在心脏按压效果方面，2步法和4步法之间没有差异。在CPR期间正确实施胸外按压是增加患者获救几率的关键。研究表明，胸外按压实施过程中的任何中断都会导致心脏按压效果逐渐降低，对接受CPR的患者预后产生负面影响。
