Quality assessment of heart compression

Objective: Monitoring of the quality of heart compressions of those employed in the emergency department using a simulator CPR software. Methodology: The results of heart compressions obtained from the CPR software were processed. The results were statistically analyzed in ANOVA method and by using t-test for paired samples. Results: We analyzed the results of heart compressions of three groups of respondents (doctor, technician, driver). We followed four parameters: the frequency of the massage, depth of the massage, hand position, and the inclination of the body during the massage. The first measurement was performed without exercise for two minutes. After a period of practice, the measurement was repeated in the same time interval of two minutes. The results show that there is no statistically significant difference between the groups, while there were statistically significant differences in the parameters within groups before and after exercise. A statistical analysis of the four parameters indicates a statistically significant difference in the depth of compression, the number of shallow compressions, as well as the inclination of the body (p<0.05) before and after exercise among the three groups. In addition to this statistical significance, in the case of the driver there was a statistically significant difference before and after exercise in the position of the hand during resuscitation. There were no statistically significant differences in measurements with a metronome and after exercise without a metronome, but the exercise with a metronome enabled the results to be good after exercise. Conclusions: In real-life situations during CPR, we focus on the course and outcome, and do not think about the parameters that affect the quality of the procedures we apply. The software simulator allows us a detailed analysis, while frequent exercise improves the quality and corrects any errors that occur during CPR. To correct the errors, it is necessary to carry out continuous training and more frequent checks on the trainer.
