Purpose: The use of mechanical compression devices may be considered as an alternative method to treat cardiac arrest. This study aimed to assess the influence of vertical location of cardiac arrest scene to survival rate. Furthermore, it set out to examine the effect of mechanical compression devices on the survival rate.
Method: This is retrospective, observational study of cardiac arrest patients from Gangdong-gu, Seoul between September 2015 and February 2016. The data were collected by 119 rescue records and cardiac arrest summary list, and the resuscitation result variables were analyzed. We also conducted a survey on 119 paramedics regarding the subjective valuation and drawback of using mechanical compression devices.
Results: The odd ratio of return of spontaneous circulation (ROSC) in vertical location of cardiac arrest scene was 0.40 (95% confidence interval, 0.17 to 0.98; p=0.044). The odd ratio of survival to admission comparing manual compression with mechanical compression was 0.73 (95% confidence interval, 0.26 to 1.99; p=0.532). A total of 54 paramedics completed the survey, and 46 (85.2%) of them answered that there was a decrease in the quality of chest compression if the scene was other than the 1st floor. Fifty-three (93.1%) replied that mechanical compression devices can be a countermeasure.
Conclusion: Vertical location of cardiac arrest scene independently effects ROSC of out of hospital cardiac arrest. However, there was no difference in the survival rate between manual and mechanical compressions.
