Abstract: Background: Out-of-hospital cardiac arrest (OHCA) remains a leading cause of mortality globally. Mechanical CPR devices, such as LUCAS-2 and AutoPulse, were developed to provide consistent and uninterrupted chest compressions, addressing the limitations of manual CPR.
Objective: This study evaluates the effectiveness of mechanical CPR devices in improving ROSC, survival, and neurological outcomes compared to manual CPR in a tertiary hospital setting.
Methods: A retrospective cohort study was conducted on 420 OHCA patients treated by paramedics. Patients were divided into two groups: mechanical CPR (n=210) and manual CPR (n=210). Primary outcomes included survival to hospital discharge, while secondary outcomes assessed pre-hospital ROSC and neurological recovery using the Cerebral Performance Category (CPC) score.
Results: Pre-hospital ROSC rates were significantly higher in the mechanical CPR group (58.6%) compared to manual CPR (45.7%, p=0.01). Survival to hospital admission was also greater (71.4% vs 60.0%, p=0.01). Although survival to discharge favored mechanical CPR (33.3% vs 26.2%), it was not statistically significant (p=0.08). Neurological outcomes were significantly better in the mechanical CPR group, with 65.7% achieving favorable CPC scores (CPC 1–2) compared to 50.9% in the manual group (p=0.04).
Conclusion: Mechanical CPR devices improve ROSC rates, survival to admission, and neurological outcomes compared to manual CPR. While survival to discharge did not achieve statistical significance, mechanical CPR remains a valuable tool in prolonged resuscitation scenarios and patient transport.
