摘要
目的观察在心肺复苏（cardiopulmonaryresuscitation，CPR）操作中应用实时反馈系统对胸外按压质量改善的效果。方法采用对照研究的方法，110名急诊科和院前急救人员利用高级复苏模型，在心肺复苏反馈技术报告系统的监测下（背对电脑显示器），按照（2015AHACPR指南》推荐要求实施胸外心脏按压2min。观察并记录每位操作者胸外心脏按压平均速率（次／min）、平均深度（cm）、胸廓回弹速率（chestcompressionre]easevelocity，CCRV）（eenti．inches／s）。在休息1h后面对反馈系统的显示屏再次进行2min的胸外按压，电脑系统记录以上参数，进行数据统计分析。结果应用反馈系统前后，有效胸外按压率分别为（20．25±26．89）％伪．（70．16±20．18）％；按压深度分别为（5．15±0．76）cm vs．（5．52±0．29）cm。按压深度不够以及按压深度过度的百分比均显著低于应用前43．64％vs．10％；14．55％vs0．09％；平均按压频率分别为（102．26±6．76）次／min强（121．29±9．89）次／min；平均按回弹速率分别为（1430．81±218．79）centi-inches／svs．（1575．62±135．71）centi-inches／s，差异均具有统计学意义（P〈0．01，n=110）。结论加强CPR质量参数的监测与实施实时反馈系统能有效提高胸外按压的质量。
Objective To observe the effect of applying CPR real-time feedback system to improve the quality of chest compression. Methods 110 staff who from emergency department and pre-hospital care practiced CPR on a resuscitation manikin for 2min according to the 2015 AHA guideline update for CPR recommended requirements. First, applied the Zoll CPR feedback technical report system but operator were back to the computer monitor. Observed and recorded each operator at an average rate of Chest compression （times/min）, average depth （cm）, Chest compression release velocity, （CCRV） （centi - inches/s） . Then practice again for 2 min chest compression in the face of the feedback system after an hour rest. The computer system recorded the above parameters and then data analysis. Results Before and after the application of feedback system, the effective rate of chest compression respe ctively was （20. 25 ± 26. 89） % vs. （70. 16 ± 20. 18）% ; Mean Compression depth respectively was （ 5. 15±0. 76） cm vs. （5.52 ±0. 29） cm. Excessive Compression depth and Compression depth were significantly lower than the percentage of the application before 43.64% vs. 10% ; 14. 55% vs.0. 09%. The mean chest compression rate respectively was （ 102. 26 ± 6. 76 ） times/min vs. （ 121.29 ± 9. 89 ） times/min ; The mean CCRV respectively was （ 1 430. 81 ± 218.79 ） centi-inches/s vs. （ 1 575.62 ± 135. 71 ） centi-inches/s, differences were statistically significant （P 〈 0. 01, n = 110） . Conclusions Monitoring and applying the CPR real-time feedback system can effectively improve the quality of chest compression.
