Abstract:
Objective:To simulate the biomechanical characteristics of the real human thoracic cavity with a multi-spring group variable damping structure, and to design a new cardiopulmonary resuscitation training manikin based on the simulated thoracic biomechanical characteristics combined with the original electronic feedback system, and to test its application effect in cardiopulmonary resuscitation (CPR) teaching.Methods:A total of 60 undergraduate students majoring in five-year clinical medicine of Batch 2019 in Naval Medical University were selected as the research objects and were randomly divided into the experimental group and the control group, with 30 students in each group. The control group used the traditional manikin for CPR training, and the experimental group used the new type of manikin for CPR training based on the control group. After the training, the two groups of personnel were assessed for single skill. The single skill was mainly manual CPR operations, including artificial respiration and chest compressions. The theory and skill operation assessment of CPR and satisfaction for teaching method in the two groups were compared. SPSS 23.0 was used for statistical analysis.Results:The students in the experimental group scored (54.33±3.09) points in the single skill operation assessment, which were significantly better than that of the students in the control group [(52.33±3.08) points], and the difference was statistically significant ( P<0.05). The follow-up questionnaire showed that the students in the experimental group had a better evaluation of the teaching and training effect of the new type of manikin. Conclusion:Compared with the traditional manikin, the new CPR manikin can simulate the CPR emergency scene of the real human body, which can effectively improve the CPR teaching effect of standardized training for medical students, and help the standardization, normalization, and popularization of CPR technology in China.
