Influencing Factors of Cardiopulmonary Resuscitation Machine in Patients with Respiratory and Cardiac Arrest and Preventive Measures
Objective To explore the factors influencing the effectiveness of cardiopulmonary resuscitation (CPR) treatment in patients with respiratory and cardiac arrest using a CPR machine,and to analyze preventive countermeasures to improve rescue success rates and patient prognosis. Methods A total of 98 patients with respiratory and cardiac arrest res-cued in the emergency department of Jiangning Hospital,Jiangsu Province,from June 2021 to March 2024 were retrospectively selected. Their clinical data were collected,and the resuscitation outcomes were observed. Patients were divided into the return of spontaneous circulation (ROSC) group and the non-ROSC group. The clinical data of the two groups were compared,and univariate and multivariate stepwise Logistic regression analyses were conducted to identify independent factors affecting the treatment efficacy. Results The ROSC rate after mechanically assisted CPR was 37.76％ (37/98). Compared with the non-ROSC group,the ROSC group had significantly lower proportions of patients aged≥65 years,time to start CPR>4 min,cardiac causes,cumulative epinephrine dose>5mg,and tracheal intubation time>180 s,while the proportion of patients with shock de-fibrillation was significantly higher (P<0.05). Multivariate stepwise Logistic regression analysis revealed that delayed initiation of CPR (OR=5.226,95％CI:2.307-11.834),cumulative epinephrine use (OR=3.814,95％CI:1.318-11.034),and prolonged intubation time (OR=3.427,95％CI:1.611-7.288) were independent risk factors for ROSC. Shock defibrillation (OR=0.211,95％CI:0.085-0.523) was an independent protective factor (P<0.05). Conclusion Delayed CPR initiation,high cumulative epinephrine dose,and prolonged intubation time are independent risk factors for ROSC,while shock defibril-lation serves as an independent protective factor. Early and reasonable measures can effectively enhance rescue success rates and improve patient outcomes.
