By means of oral instructions, the device tells the user what to do when trying to reanimate the patient. Market managers and security staff have also taken a training course on the proper use of the device.

The defibrillator has been installed in the El Rancho Grande bar, in Bridge 2 of the Market, thanks to the cooperation of this establishment. A regular fixture in many public venues, this is the first such device to be set up in Mercabarna. The Central Fish Market was chosen because it is a venue where many people gather in a short interval of time.
