Chest wall mechanics during mechanical chest compression and its relationship to CPR-related injuries and survival

Injuries associated with mechanical chest compressions and active decompressions after out-of-hospital cardiac arrest: A subgroup analysis of non-survivors from a randomized study

“…In a OHCA study by Azeli Y et al they determined the CPR compression force variation (CFV, the difference between the maximum and minimum force values of the first 30 minutes of LUCAS CPR) and its relationship with chest injuries and survival. 13 The median number of rib fractures, sternum fractures, bilateral fractures were higher for high positive chest compression force variation (CFV, ≥95 N), and high negative CFV (<−95 N) compared to low CFV (<95 N). The variation was positive when the maximum force value was observed after the minimum value along the CPR duration and negative when maximum was observed before the minimum value.…”

Improving survival from mechanical chest compression resuscitation

“…It was with great interest that we read the study by Azeli et al on mechanical chest compression related injuries and survival. 1 The authors found that high positive and negative compression force variations correlated with diminished survival to hospital admission compared to low compression force (16.7% vs 36.6%; p = 0.105). 1 …”

“… 1]. , 2]. Compressions performed with the LUCAS TM mechanical compressor (Stryker/Jolife AB, Lund, Sweden) meet the requirements of high-quality CPR, but in large randomised clinical trials that have been conducted so far it has not been shown to improve survival.…”
