Sadly this "fixit" is NOT REAL.
I saw this one a month or so ago, and asked a Clinical Nurse Specialist about it. She runs the A&E at Royal Melb and she could not stop laughing, saying it was the best bit of bull dust she has seen in ages.
As most folks know, a heart attack is essentially caused by blood vessels on the heart being clogged (THIS is the five minute version, okay..) and resulting in heart muscle death.
Such events cause a change in the electrical activity of the heart, and when it gets out of synch - a process called fibrillation, where the heart is essentially behaving like a writhing bag of worms, no blood is effectively being pumped around the body.
CPR simply keeps the blood pumping around, until the electrical rhythm can be jump started using a defibrillator.
If the patient has a cardiac arrest, and is non breathing (and is assumed therefore to have no pulse) the patient will need to have their breathing AND heart artificially carried out for them until defibrillation takes place.
Now the figures (from St John Ambulance).. if defibrillation takes place within ONE minute of the arrest, there is a 90% survival rate. This survivability drops at the rate of 10% per minute, so making a 10 minute arrest with CPR being applied almost non survivable.
For those who attended the CASA talk at Shepp last year, they may remember the good doctor who stated that for "30% of heart attack patients, the first symptom is sudden death."
For those a bit stunned, may I suggest having a chat with your GP (and having a checkup as well) and for those interested in learning more about it, contact your state branch of St John Ambulance, who are perhaps the leaders in teaching first aid, and advanced resus skills including how to use defib machines.
BTW, St Johns in Victoria provide a volunteer first aid service to many community and sporting events, and are a common sight at the MCG and other major venues. St Johns is also behind moves to establish defib machines that are simple to use at places such as the G, where they have already saved a number of lives.
