Objective: To explore the application effect of emergency rescue capability intervention among students in a university in Beijing. Methods: A total of 900 students from a university in Beijing in 2023 were selected as the research objects. Emergency rescue capability training was conducted from March 2023 to June 2023, once a month. The students’ mastery of emergency rescue before and after the intervention was analyzed. Survey questionnaires were distributed to all college students to understand their channels and willingness to acquire emergency rescue knowledge. Results: A total of 886 valid questionnaires were collected in this study. The highest proportion of knowledge about China’s general emergency telephone number and how to dial the emergency rescue hotline was 100.00%. Among the strategies for dealing with cardiac arrest in CPR, the highest proportion was 336.34%. Among the four major first aid techniques of hemostasis, bandaging, fixation, transportation, the highest proportion of knowledge about the use of rubber band signs was 31.71%. Among the first aid techniques for heatstroke, poisoning, fire, and sharp instrument injuries, the principle of emergency treatment for severe gas poisoning had the highest proportion of 41.42%, showing significant differences. College students mainly acquire knowledge of emergency rescue capability through TV programs, health education lectures, and the internet. Around 61.40% of college students hope to learn more about prevention and control knowledge. Conclusion: After the intervention of emergency rescue capability, the emergency rescue capability of college students in this university has been significantly improved, showing a strong training effect, which is worthy of promotion.
