Objective By taking cardiopulmonary resuscitation (CPR) resident standardization training skills practice as an example,to explore how to improve the ability of resident operating on the clinical skills.Methods 58 resident physicians in the hospital standardized training were selected,and through training and assessment of cardiopulmonary resuscitation skill training,the result was compared,and statistical analysis was made on the overall pass rate,the performance after the training,and the pass rate of operation.Result Comparison of the data was done by the t test,and pass rate by chi square result 48 people passed the training and examination,and the pass rate was 82.76％.The operation scores before and after training were:General (78.5 ± 6.44) vs.(89.2 ± 6.12),Department of gynecology and Obstetrics (74.3 ± 6.54) vs.(87.0 ± 6.34) of (70.6 ± 6.78) vs.(87.3 ± 6.31),rehabilitation medicine (70.2 ± 6.81) vs.(85.6 ± 6.77),Department of Stomatology (69.80 ± 7.07) vs.(82.80 ± 6.89),psychiatric (69.4 ± 7.19) vs.(80.4 ± 6.91),Department of medical imaging (69.30 ± 7.20) vs.(78.80 ± 6.94),(64.00 ± 7.25 test vs.) (76.5 ± 6.99),and the differences were statistically significant.After the training,the average score of the general professional training was 89.2,the highest score,while the average score of students trained in professional inspection department was 76.5 points,the lowest score.Chest compressions and artificial respiration,electrode plate installation project operation were the worst.Students pressed 80 times/min before but now increased to 90 seconds;as for artificial respiration,students often extended more than 30 seconds;the electrode plate installation project operation,extended more than 25 seconds.Conclusion The pass rate of different professional training and the performance before and after professional training have differences,so theory and practice need to be combined to carry out scientific and reasonable training so as to improve the train-ing residents' clinical skills.
