You see a person clutch their chest, lose all colour in their face, and suddenly fall to the ground, unconscious while displaying no signs of life. The signs mimic that of someone suffering from a Sudden Cardiac Arrest (SCA). You know CPR, but where’s the closest defibrillator?
Reducing the time it takes to locate an Automated External Defibrillator (AED) is key. If an AED is applied to a sudden cardiac arrest victim within the first minute of collapse, their chance of survival is 90%. For every minute that passes, their chance of survival drops 10%, leaving a 10 minute ‘window of opportunity’.
Not every defibrillators location is registered. The location varies in every town, but defibs are most common in large public places, such as:
Many of these locations are subject to operating hours. For example, you will only have access to the defibrillator located in the foyer of your public library during the library’s operating hours. This means the closet defib to you depends on the time of day. If you need access to a defib, think about where you are, if you are not sure, send someone else to retrieve a defibrillator while CPR is immediately administrated.
Still unsure where to find your nearest defib? Contact your local council and ask for defibrillator locations. Here is an example of defibrillator locations in Brisbane City (last updated in 2010).
Defibrillation works by delivering an electrical current through the heart muscle via the defibrillation pads. All electrical activity in the heart is temporarily ceased in the hope that when it returns it will be in a rhythm compatible with an effective pumping motion.
Survival rates are highest when defibrillation is delivered within the first few minutes of the time of collapse. Through greater defibrillator availability and knowledge of location, survival rates of SCA victims will improve.
D = Danger. Check for danger before approaching the causality. Things to check for may include live wires, exposed needles, or flammable liquids. Your safety ALWAYS comes first.
R = Response. Attempt to get a response from the causality by asking them to say their name or squeeze your hand.
S = Send for Help. If there is no response, now is the time to call 000. If there is other people present at the scene of accident, send someone to locate the nearest defibrillator.
A = Airway. Is the airway clear? Check to make sure the causality has nothing in their mouth, such as broken teeth, food or vomit.
B = Breathing. Once a clear airway is established, check to see if the causality is breathing.
C = Compressions. Commence chest compressions at a rate of 30 compressions to 2 breaths. You should be pushing at the depth of 1/3 of the victims chest and at a rate of 100 chest compressions per minute (this will be interrupted by administrating the breaths).
D = Defibrillator. Apply the defibrillator following the voice prompts. If emergency medical staff are there applying the defib, follow their instructions.
