摘要
目的探讨心肺复苏（CPR）中胸外心脏按压持续时间与按压有效性的关系。方法利用心肺复苏模型对195名医务人员胸外心脏按压持续时间与按压有效性的关系进行研究。结果随着胸外心脏按压持续时间的延长,出现按压偏轻的人数和次数逐步升高。到第5个循环时,有52.25%的操作者至少出现1次以上按压偏轻。第1-5循环中,偏轻的按压分别占4.63%、11.49%、14.34%、22.20%和25.31%。结论为了保证CPR质量,医务人员在进行CPR时,应每4-5个循环更换按压者。
Objective To study the effect of the cycles of CPR on the quality of chest compressions. Methods To observe the quality of chest compressions in 195 medical personnel by using adult CPR simulator. Result The shallow compressions increased from the first CPR cycle to the fifth CPR cycle, accounting for 4.63%, 11.49%, 14.34% ,22.20% and 25.31% of the total compressions, respectively. Conclusion It is reasonable to switch the compressor after 4 to 5 cycles of compressions.
