On the recommendation of a colleague, you are reading the PARAMEDIC trial that compared mechanical CPR using the LUCAS-2 device, with conventional manual CPR.

The methods state that each ambulance was assigned to provide one of the interventions, and eligible patients would receive either mechanical or manual CPR depending on which ambulance arrived first.

The primary outcome was survival at 30 days; this was assessed by a researcher who was not aware of which arm of the study (mechanical or manual) the patient was in.
