目的：尽管心肺复苏术指南得到了广泛的培训，但心肺复苏术通常执行得很差。我们探讨了心肺复苏指南知识与性能（按压率、按压深度、按压与通气比和通气量）之间的关系。方法：从城市系统的31个急救站中随机抽取26个急救站，抽取60名专业急救人员。一个记录人体模型和视频模型被用来评估性能在一个标准化的情况下，和一个调查被用来评估指南的知识。根据2000年的国际CPR指南，将调查和性能结果前瞻性地分类为正确或不正确。用逻辑回归建立关系模型。协变量包括多年的工作经验，CPR性能的频率，ALS与BLS EMT level.Results：在56%（33/59）的试验中，按压率在80和120分钟（-1）之间。压缩深度为1.5-2英寸。39%（23/59）的患者压迫与通气比接近15：2（25/59），13%（8/60）的患者通气量为800-1200 cm 3。正确掌握心肺复苏指南与胸外按压率和按压通气比的良好表现相关。校正OR（95% CI）为4.6（1.2-18.1）压缩率为1.7（0.4-6.5）对于压缩深度，4.5（1.1-18.5）压缩通风比，和9.0（0.2-351）。结论：虽然指南的准确知识与CPR某些方面的正确性能的几率增加有关，但总体性能仍然很差。(c)2005 Elsevier爱尔兰有限公司AtI。rights reserved.
Objective: Despite widespread training with CPR guidelines, CPR is often poorly performed. We explore relationships between knowledge of CPR guidelines and performance (compression rate, compression depth, compression to ventilation ratio, and ventilation volume).Methods: Sixty professional EMTs were sampled at 26 randomly ordered EMS response stations from an urban system of 31 stations. A recording manikin and video model were used to assess performance in a standardized scenario, and a survey was used to assess guideline knowledge. Survey and performance outcomes were categorized prospectively as correct or incorrect based on the International CPR Guidelines from 2000. Relationships were modeled with logistic regression. Covariates included years of work experience, frequency of CPR performance, and ALS versus BLS EMT level.Results: Compression rate was between 80 and 120 min(-1) in 56% (33/59) of trials. Compression depth was 1.5-2 in. in 39% (23/59), compression to ventilation ratio approximated to 15:2 in 42% (25/59), and ventilation volume was 800-1200 cm(3) in 13% (8/60). Accurate knowledge of the CPR guidelines was associated with better performance of chest compression rate and compression to ventilation ratio. Adjusted OR (95% CI) were 4.6 (1.2-18.1) for compression rate, 1.7 (0.4-6.5) for compression depth, 4.5 (1.1-18.5) for compression to ventilation ratio, and 9.0 (0.2-351) for ventilation volume.Conclusions: Although accurate knowledge of guidelines is associated with increased odds of correct performance of some aspects of CPR, overall performance remains poor.
