The same Annier CPR simulated dummies were used in the test. Statistical processing The SPSS15.0 GX15-070 software system was used in data processing. The measured materials were expressed with x- ± s, and analyzed by t Test; the calculated materials were tested by χ2, and the influence factors were analyzed by multi-factor Logistic repression method, and P<0.05 referred to the distinct

difference in statistics. Results According to the testing indexes of compression depth, frequency and released pressure between compressions, 86.4% of the medical volunteers met the standard requirements of performance, and only 31.9% of the medical workers in the compared group could Inhibitors,research,lifescience,medical meet the standard requirements of performance. In terms of tested unilateral indexes, the pass rate of volunteers was much higher

than that of ordinary medical workers, as could be shown in Table Inhibitors,research,lifescience,medical ​Table11. Table 1 Comparison of Two Groups in Performance Qualities There were no distinct differences between the two groups in the average number of practical compression per minute. Compared with that of ordinary medical workers, Inhibitors,research,lifescience,medical the time of ventilation used by the volunteers was shorter. There was no difference between the two groups in the total time used in 5 CPR, which were 118.4±18.5s and 116.0±5.4s. There was no distinct difference between the two groups in the number of practical compression per minute, as could be shown in Table ​Table22. Table 2 Comparison of Number of Practical Compression Per Minute & Time Inhibitors,research,lifescience,medical of Compression and Ventilation (x- ± s) Note: Compared with those ordinary medical workers/

doctors t=4.41, *P<0.05 The factors which could influence CPR performance were given parameters, including gender (male=0, female=1) and age (≤30y=0, 31y~45y=1, ≥46y=2); proper hand skill, posture and position, and attending repeating standard training were given 0, and on the contrary they were given 1.The tested results of multi-factor parameters were put into Logistic Repression Model and analyzed. The results showed that such factors as the hand skill, posture of compression and repeating training had clear relationship with CPR performance qualities, Inhibitors,research,lifescience,medical as could be shown in Table ​Table33. Table 3 Logistic Repression Analysis of CPR Performance already Discussion CPR is one of the most important emergency techniques. Proper, immediate and effective CPR is the key to resuscitation, and it should be popularized as an important item in public health care. The emergency work is very important in meetings, ceremonies, sports games and so on. Before Mt. Taishan International Mounting Festival was held, the medical volunteers were experienced repeating trainings of emergency theories and techniques for six months. The study selected 52 medical volunteers at random and tested their CPR performance, and compared them with those of ordinary medical workers who had been working in emergency department in 3 hospitals of Taian.
