mask fixation in the lateral position is difficult during CPR.
the aim of this study is to compare the lateral CPR for the use of bag-valve mask by single paramedic rescuer as well as over-the-head CPR on the chest compression and ventilation on the manikin.
Mazandaran University of Medical Sciences. The design of this study was a randomized cross-over trial.
participants learned a standardized theoretical introduction CPR according to the 2010 guidelines. The total number of chest compressions per two minutes was measured. Total number of correct and wrong ventilation per two minutes was evaluated.
we used Wilcoxon signed-rank test to analyze the non-normally distributed data in dependence groups A. P-value of more than 0.05 was considered to show statistical significance.
there were 100 participants (45 women and 55 men) who participated in the study from September to March, 2011. The compression and ventilation rate in lateral CPR was lower than OTH CPR. Around 51% of participants had correct chest compression rate more than 90 beats per minute in lateral CPR and 65% of them had equal or more than ten correct ventilations per minute.
in conclusion, this study confirmed that in a simulated CPR model over-the-head position CPR led to a better BLS than the lateral position CPR by a single paramedic student with a BVM device. We also concluded that by this new BVM fixation method on the face of the patients in the lateral position CPR can be a good alternative over-the-head mask fixation by a single trained rescuer.
在心肺复苏过程中，侧卧位时面罩固定困难。
本研究旨在比较单名护理人员救援者使用球囊面罩进行侧卧位心肺复苏以及进行头罩式心肺复苏对人体模型胸部按压和通气的影响。
马赞德兰医科大学。本研究设计为随机交叉试验。
参与者根据2010年指南学习标准化的理论心肺复苏介绍。测量每两分钟的胸部按压总数。评估每两分钟正确和错误通气的总数。
我们使用Wilcoxon符号秩检验来分析相关组A中的非正态分布数据。P值大于0.05被认为具有统计学意义。
2011年9月至3月有100名参与者（45名女性和55名男性）参与了该研究。侧卧位心肺复苏的按压和通气率低于头罩式心肺复苏。在侧卧位心肺复苏中，约51%的参与者胸部按压率正确，超过每分钟90次，其中65%的参与者每分钟有十次或更多次正确通气。
总之，本研究证实，在模拟心肺复苏模型中，对于单名护理专业学生使用球囊面罩通气装置进行心肺复苏，头罩式心肺复苏比侧卧位心肺复苏能带来更好的基础生命支持。我们还得出结论，通过这种新的球囊面罩通气装置固定方法，在侧卧位心肺复苏中对患者面部进行固定，对于经过培训的单名救援者来说可以是头罩式面罩固定的一个良好替代方法。
