In Regina, EMS arrives on the scene about six minutes after being called. This is considered one of the best response times in Canada. So, even though paramedics are equipped with a defibrillator, the response time may not be fast enough to save a victim experiencing Sudden Cardiac Arrest.
Survival rates are highest for patients who receive a defibrillation shock within three minutes of collapse. This almost requires that an AED be on-site anywhere groups of people gather and that trained responders are available. Remember, 90-95 percent of all SCA victims die. Survival rates can rise to 70 percent or more when an AED program is in place.
Therefore, sites that are equipped with AEDs can defibrillate someone who is experiencing Sudden Cardiac Arrest before paramedics even arrive - and could potentially save his or her life.
