Objective To analyze the current status of cardiopulmonary resuscitation(CPR)in patients with out-of-hospital cardiac arrest(OHCA)in Haikou,and to explore ways to improve the success rate of the effectiveness of CPR.Methods a total of 416 patients who underwent CPR outside the hospital in Haikou city from August 2019 to August 2022 were selected.Based on the Utstein model,the implementation of pre-hospital CPR chain of survival was compared,the factors affecting prognosis were analyzed,and the risk factors affecting the effectiveness of cardi-ac arrest resuscitation were analyzed by Cox regression.Results After excluding the confounding factors,a total of 416 subjects were finally included in this study,of which 38 patients were effectively resuscitated and 378 patients were ineffectively resuscitated.There was a statistically significant difference in gender,age,place of occurrence,e-mergency response time,initial heart rhythm type,whether witnesses CPR,and whether epinephrine was given or not between 2 groups(P＜0.05).Multivariate logistic regression analysis showed that the first aid response time(OR=0.750,95％CI was 0.640～0.891,P＜0.001),witnessed CPR(OR=0.063,95％CI was 0.006～0.648,P=0.02),initial rhythm type(OR=0.105,95％CI was 0.024～0.449,P=0.002)were independent influencing fac-tors for the effectiveness of CPR in patients with out-of-hospital cardiac arrest.The results of Cox regression analy-sis showed that emergency response time was a risk factor of affecting effective resuscitation,and the longer the e-mergency response time was,the lower the patient survival rate and the greater the risk index.Conclusion Emergen-cy response time,witness CPR,and initial heart rhythm type are independent factors of affecting the effectiveness of CPR in OHCA patients.OHCA has formed certain regional characteristics in epidemiology,and the improvement of the success rate of pre-hospital resuscitation depends on further improving each key link of the out-of-hospital surviv-al chain and building a national first aid system.
