This retrospective cohort study compared LUCAS®-assisted mechanical CPR with high-quality manual chest compressions in overweight and obese patients experiencing in-hospital cardiac arrest (IHCA).

Summary of Findings:

No Improvement in Survival: The use of the LUCAS mechanical CPR device did not improve survival outcomes at either the 24-hour or 60-day mark when compared to high-quality manual compressions.

BMI Independent: The effectiveness (or lack thereof) of the LUCAS device was independent of the patient’s Body Mass Index (BMI) within the overweight and obese categories.

Study Design: This was a multicenter retrospective cohort study conducted across seven Mayo Clinic hospitals. The analysis used Inverse Probability of Treatment Weighting (IPTW) to adjust for differences in patient demographics, arrest location, and pre-existing health conditions (comorbidities).

For overweight and obese patients suffering an in-hospital cardiac arrest, the use of the LUCAS mechanical CPR device does not offer a survival advantage over standard high-quality manual chest compressions.
