We aimed to analyze demographic and clinical characteristics, and outcomes of patients aged 65 years and older who underwent cardiopulmonary resuscitation. Materials and Method: Data of eldery patients who underwent cardiopulmonary resuscitaion in the emergency department between January 2013 and December 2019 were scanned retrospectively. Patients characteristics, cardiac arrest location, and outcomes were recorded and analyzed. Results: In total, 224 patients with mean age of 76.51 ± 8.23

... s. A return of spontaneous circulation rate was 46.4%, and the 30-day survival rate was 7.6%. A return of spontaneous circulation rate was decreased with age. Some 86.7% of the patients had at least one comorbidity and cancer was the most common. The mean duration of cardiopulmonary resuscitation was 33.28 ± 22.16 minutes. The mean cardiopulmonary resuscitation duration in the patients who had an return of spontaneous circulation and survived was significantly lower. The pH and lactate values of the patients were found to be statistically different in patients who had a return of spontaneous circulation. The most common cardiac arrest cause was infectious diseases in 72 (32.1%) patients and the most common diagnosis in living patients was cardiac causes. Conclusion: As the number of elderly individuals increases, and the number of comorbidities increase, the number of emergency department admissions as well as the incidence of in-hospital and out-of-hospital cardiac arrest will also increase in parallel with the increase in life expectancy.
