Expansion of the use of external defibrillators

In a cardiac arrest, the use of defibrillators to increase the chances of survival. Widely disseminated in public places across the Atlantic, the use of these devices remained limited in France. But a new decree has changed the situation.

There are each year in France between 30,000 and 60,000 heart attack. Against this scourge and in case of ventricular fibrillation, the prompt issuance of a suitable electric shock can restore a normal heart rhythm and save the person. External defibrillators today to do this with ease. Their dissemination should rapidly increase.

Benefits against heart attacks
We know that more relief are involved early, the more the chances of survival. Every minute that passes reduces the chances of 10%. Ventricular fibrillation (VF) is spontaneously lethal. In the absence of support in less than 10 minutes, the chances of survival are stabilisation. On the other hand, if the victim receives an electric shock during the first minute, they are greater than 90%. Low weight and small size, automatic or semi-automatic equipment are able to analyse the heart rate prior to the issuance of a life-saving shock, a system of possible malfunction and even assistance to the actions to be carried out by the vocal instructions.

The three main types of external defibrillators
Semi-automatic external defibrillators record heart rate and ask permission to send the electric shock to defibrillate if necessary;
Automatic external defibrillators record heart rate and send the electric shock to defibrillate if necessary;
Manual external defibrillators are content to provide an electrical shock. Users must decide only the need for defibrillation.

In the United States, the use of these devices is gradually extended to public places. This decision is largely motivated by a large study1, that improper manipulations are rare and these devices by trained volunteers is used to near – double the number of people who have survived a heart attack (23.4% vs. 14.1%). Facing a cardiac event, it is urgent to call the 15, and to initiate cardiopulmonary resuscitation techniques. And we saw an external defibrillator to increase these opportunities.
