AbstractPurpose of review
The aim of this review is to update and discuss the use of mechanical chest compression devices in treatment of cardiac arrest.Recent findings
Three recently published large multicenter randomized trials have not been able to show any improved outcome in adult out-of-hospital cardiac arrest patients when compared with manual chest compressions.Summary
Mechanical chest compression devices have been developed to better deliver uninterrupted chest compressions of good quality. Prospective large randomized studies have not been able to prove a better outcome compared to manual chest compressions; however, latest guidelines support their use when high-quality manual chest compressions cannot be delivered. Mechanical chest compressions can also be preferred during transportation, in the cath-lab and as a bridge to more invasive support like extracorporeal membrane oxygenation.
