Three Part Question

In [adult cardiac arrests] admitted to the Emergency Department. Does the [use of mechanical chest compression devices vs manual chest compressions] improve [ROSC]

Clinical Scenario

Over the years there has been increasing evidence to support the benefit of effective chest compressions in the management of patients in cardiac arrest. In some areas, mechanical chest compression devices have been used in order to facilitate this. I want to explore the evidence surrounding these devices and their use / introduction in the Adult Emergency Department.
