the survey respondents had the highest pass rate of57.29 % for the CPR basic knowledge section and the lowest pass rate of 28.00% for the airway management and artificial respiration knowledge section.The results of univariate analysis showed that the differences in the pass rate of CPR knowledge were statistically significant（P<0.05） among survey respondents with different ageeducation occupation
