In my opinion, it is not necessary to insist that we have the same brand of defibrillator electrodes, AED monitors and defibrillators. In Quebec, we had a call for tenders to supply AEDs and ambulance monitors for the entire province, which is a good thing. It is easier to sync the AEDs with the ambulance monitors.
What really matters is how quickly the first shock can be administered. If the defibrillator electrodes or the monitor are not the same as those used in our region, the defibrillator electrodes can be changed later. The delay is short and occurs at the beginning. I think that we do not have to insist that we have the same monitors. We can consider the cost and which one is more useful, or use other criteria. My colleague spoke earlier about devices whose defibrillator electrodes can better tolerate Quebec's temperature differences. That might be more useful.
