AEDS are kept in many public places like airports, supermarkets, train stations and public attractions. Anyone can use an AED, and it will never shock someone that doesn't need an electric shock. The machine will analyse someone's heart rhythm and then you use the visual prompts to guide you through each step. When a person suffers from a SCA, every second counts. The majority of people are scared to administer CPR to someone suffering from a SCA because they are afraid they may cause further damage.
With the right knowledge and training, people would feel more confident about administering CPR. Ensure the area you are in is safe and free from danger. You must call for help: if you are in a busy area ask a passer-by to call the emergency services; if you are in a remote location use your mobile to make the call. Use whatever resources you have available to request an ambulance and locate a defibrillator. This will help the heart pump blood to the brain and other vital organs.
Place the heel of your hand on the centre of the person's chest and place your other hand directly on top, interlacing the fingers. Straighten your arms and begin to press down around 2 inches, or a third of the chest diameter, keeping a steady rate for 30 compressions. Tilt the victim's head back and lift the chin using two fingers. Find training external icon or a course external icon near you.

Heart attacks can mimic cardiac arrest in their suddenness, and intensity, but heart attacks can also present fairly mild symptoms that can play out over hours, days or even weeks. Heart attacks occur when the flow of oxygenated blood from the lungs to the heart is blocked, usually by plaque buildup within the arteries leading to the heart.
This condition is known as arteriosclerosis and unless this blockage is removed, the area of the heart serviced by that artery will quickly begin to die. Heart disease is often connected to incidences of heart attack, but they can also be caused by coronary spasms that interrupt the flow of blood through an artery and into the heart. During a heart attack, the heart generally does not stop beating completely and it has been shown that symptoms of a heart attack can vary between males and females.
Neither of these is the case with actual cardiac arrest. This difference is a critical one, because once the heart stops beating entirely the victim is only minutes away from irreversible brain injury and death. With a heart attack, there may be time to get a victim to a hospital, or call Cardiac arrest is an immediate threat and must be handled immediately.
A broken rib is relatively easy to fix, a brain that has suffered several minutes of oxygen deprivation is not. It is important to understand the limitations of CPR as a life saving technique. Despite what popular entertainment would have you believe, even when properly performed within seconds of a cardiac arrest in a hospital with all necessary equipment and capabilities, only about fifty percent of all arrest victims survive the initial event.
Fewer still will survive long enough to leave the hospital and a good percentage of those will suffer some degree of neurological impairment. Why such a low survival rate?
It is impossible to know why the person has entered as a state of arrest, and that is a crucial component of proper treatment. Even discounting that, it is unrealistic to expect a given individual to be able to diagnose and properly treat another given individual who just happens to arrest within their vicinity.
Chest compressions and any accompanying rescue breaths are intended only to buy time for the EMTs to arrive and take over life saving efforts.
