Abstract:
Objective:Based on the forgetting curve principle to construct a model for the popularization of cardiopulmonary resuscitation among college students and validate its effectiveness, providing reference for the promotion of cardiopulmonary resuscitation.Methods:A randomized controlled trial was conducted. In October 2021, a multistage random sampling method was used to select 262 freshmen and sophomores from the School of Mathematics and Physics at Leshan Normal University as the control group, and 262 freshmen and sophomores from the School of Electronic Information and Artificial Intelligence as the experimental group.The control group received conventional training, while the experimental group, in addition to conventional training, received cardiopulmonary resuscitation retraining based on the Ebbinghaus forgetting curve at three time intervals: within 1 week, within 1 month, and within 1 to 6 months after training. The retraining included online self-learning, on-site observation reinforcement, and social practice sublimation. The cardiopulmonary resuscitation knowledge awareness rate and cardiopulmonary resuscitation skill assessment of the two groups were compared before training, immediately after training, and 6 months after training.Results:The final number of participants was 256 in the control group (126 males and 130 females) and 224 in the experimental group (110 males and 114 females). There were no statistically significant differences in cardiopulmonary resuscitation knowledge awareness rate and cardiopulmonary resuscitation skill scores between the two groups before and immediately after training (both P>0.05). Immediately after training, the average cardiopulmonary resuscitation knowledge awareness rate in the experimental and control groups were 91% (1 626/1 792) and 88% (1 806/2 048), respectively, which were significantly higher than the pre-training rates of 55% (989/1 792) and 55% (1 129/2 048) ( χ2=8.46, 7.30, both P<0.01). The cardiopulmonary resuscitation skill scores were (42.00 ± 3.55) and (41.68 ± 3.40), respectively, higher than the pre-training scores of (15.41 ± 4.85) and (15.92 ± 4.66) ( t=84.47, 45.56, both P<0.05). Six months after training, the awareness rates of determination of consciousness and cardiac arrest judgment, cardiopulmonary resuscitation steps, chest compression location, frequency, depth, and the ratio of chest compressions to artificial ventilation in the experimental group in college students were 90% (201/224), 93% (208/224), 92% (206/224), 93% (208/224), 89% (200/224), and 94% (210/224), respectively, higher than those in the control group, which were 62% (158/256), 71% (182/256), 77% (198/256), 73% (186/256), 70% (178/256), and 69% (176/256) ( χ2 values were 4.21-7.03, all P<0.01). The cardiopulmonary resuscitation skill score in the experimental group was (49.77 ± 3.68), higher than the control group′s (34.95 ± 4.79) ( t=38.25, P<0.01). The proportion of students confident in using cardiopulmonary resuscitation to save others was 92% (206/224) in the experimental group, higher than 58% (148/256) in the control group ( χ2=7.68, P<0.01). Six months after training, the cardiopulmonary resuscitation skill score in the experimental group was (49.77 ± 3.68), higher than the immediate post-training score of (42.00 ± 3.55), whereas the control group's cardiopulmonary resuscitation skill score was (34.95 ± 4.79), lower than the immediate post-training score of (41.68 ± 3.40) ( t=22.74, 18.33, both P<0.01). Conclusions:The cardiopulmonary resuscitation popularization model for college students based on the forgetting curve is conducive to mastering cardiopulmonary resuscitation knowledge and skills among trained college students, enhancing their confidence in using cardiopulmonary resuscitation techniques to rescue others. Moreover, it helps save the human, financial, and material resources required for cardiopulmonary resuscitation training to a certain extent and is worthy of promotion.
