An international award-winning trial by Gates et al (2017) evaluated the effectiveness of a mechanical chest compression device over standard methods of care for patients presenting in cardiac arrest.


This was a randomised control trial across 4 ambulance services within the UK using metrics such as survival and disability rates post arrest. Patients were randomised into receiving mechanical chest compression or manual chest compressions according to the first trial vehicle to arrive on scene.  The authors concluded that there is no clear advantage of the device over standard approaches.
