If it is a shockable rhythm, the AED will analyze and defibrillate as needed. Continue CPR when not analyzing and/or shocking.
It is around 6 seconds!
A blockage in one or more of the arteries supplying blood to the heart muscles.
No, it may not be over. If the police are conducting an investigation and gathering evidence and it implicates you, they can arrest you at a later time.
No, they are not the same (I have given the definitions of both below; this should help you know what each is and what is the difference between the two). Heart attack: Is caused when there is a blockage in the main arteries (coronary arteries) of the heart. Cardiac Arrest: occurs when the heart suddenly stops beating. Sorry, but Cardiac Arrest does not usually occur when the heart "suddenly" stops beating. Cardiac arrest is the worst manifestation of cardiac compromise from an acute coronary event. It happens for a number of reasons, for example if a person has had extensive bleeding and there's not enough blood within the body for the heart to pump, or when the pumping action of the heart becomes ineffective. Maybe the electrical impulses have been disrupted or the heart is not responding properly to the electrical impulses and is "twitching", most commonly known as ventricular fibrillation. That's where CPR and Automated External Defibrillation come in. If cardiac arrest occurred when the heart "suddenly stopped beating" CPR and AED's would be mostly ineffective. Time is of essence. CPR needs to be started w/in 10 minutes of the fibrillation attack/cardiac arrest, or chances are it will be too late for resuscitation. Severe brain and heart damage will have occurred by that point. Cardiac arrest victims are sometimes said to have suffered "sudden death" but that means that the patient died within one hour of the onset of the signs and symptoms. In "sudden death" autopsies typically show the patient did not really have an actual cardiac arrest but usually had significant artherosclerotic heart disease
Possibly
Yes, CPR started within 4 - 6 minutes after a heart attack when no signs of life are present will give the person a good chance of survival. As time goes beyond 6 minutes, chances of survival decrease about 10% per minute.
Longest Cardiac ArrestThe longest cardiac arrest lasted four hours in the case of fisherman Jan Egil Refsdahl (Norway), who fell overboard off Bergen, Norway, on December 7, 1987. He was rushed to Haukeland Hospital after his body temperature fell to 750F (240C), and his heart stopped. He made a full recovery after being connected to a heart-lung machine. My name is Sean Blackman.I believe the answer is at least 18 hours after death.
Is There a Difference Between a Sudden Cardiac Arrest and a Heart Attack? * A heart attack and sudden cardiac arrest are not the same thing. * A heart attack is technically known as myocardial infarction, although a person suffering a heart attack certainly has an increased risk of a sudden cardiac arrest. * The term cardiac arrest is also used to describe the sudden loss of function of the heart, as result of an abrupt disturbance in the heart's rhythm. It can occur in a person with or without heart disease. The basic difference is summarized below: Who can be affected by Sudden Cardiac Arrest? * People often ask who can be affected by sudden cardiac arrest, anticipating it is the fate of the elderly. Although the frequency and risk of SCA certainly increases with age it can occur without warning or symptoms to anyone, even teenagers. * According to the Australian Resuscitation Council an estimated 30,000 people a year suffer sudden cardiac arrest. Although pre-existing heart disease is a common cause for cardiac arrest, many victims never previously exhibit heart problems. * The survival rate for SCA without immediate treatment is low in the vicinity of 5 to 10 %, whereas survival rates well above 50% have been achieved following successful implementation of CPR and defibrillation, the shorter the time span of treatment the higher the survival rate. Is it possible to reverse the effect of sudden cardiac arrest? Yes, it is entirely possible to reverse the effect of a sudden cardiac arrest, particularly if the unconscious victim receives immediate aid by restoring the circulation with cardiopulmonary resuscitation (CPR) and delivery of defibrillation to restore the normal heart rhythm. If these life saving measures are delayed the prospect of a complete recovery diminishes. HEART ATTACK Cause: An occlusion or blockage in an artery that supplies blood to the heart - typically the coronary artery. Once the artery is blocked the heart muscle dies as a result of oxygen deprivation, resulting in a heart attack Warning Signs: Chest and arm pain, upper abdomen and jaw pain also common, sweating, weakness, dizziness, nausea, vomiting are all common symptoms Patient Response: Usually remains conscious and alert, usually distressed and anxious. Survival Prospects: Generally good, with appropriate treatment SUDDEN CARDIAC ARREST Cause: An abnormal or irregular heart rhythm (cardiac arrhythmias) occurs. Instead of the heart beating in a coordinated fashion, the ventricles (lower chambers) quiver or wobble - a process known as ventricular fibrillation, resulting in a cardiac arrest Warning Signs: Sudden collapse, usually no detectable pulse Patient Response: Unconscious and totally unresponsive, usually no pulse, and not breathing Survival Prospects:Generally poor 90+% will die unless CPR and defibrillation is administered within 10 minutes of collapse. Some people simply don't respond to treatment because of underlying medical conditions Page 12, Sensitive Hearts Newsletter Newsletter, Summer 2005-06 Sensitive Hearts is a publication of the Australian Sudden Arrhythmia Death Syndromes (SADS) Foundation. The primary purpose of this publication is for general information only and is not to be used as medical advice, diagnosis or treatment.the common language term "heart attack" usually refers to myocardial infarction, not cardiac arrest.
I don't know. but on April 16, 2006 Easter Sunday I had a cardiac arrest. My wife found me and gave me a cardial thump ( but hit me in the back) over and over. She thought I was Choking. This revived me. When the ambulance arrived. I had another cardiac arrest and flat lined. The paramedic then shocked me. when i came back, after few minutes it happened again. All in All i was shocked 65 plus times that day. if not shocked each time i would have died. though each time i went out because of v-fib one shock would bring me back. but every few minutes i would go back into v-fib. I have been diagnosed with malignant sudden death arrythmias. Mark, North Carolina
Trans fat. It clogs the arteries and veins and can cause a heart attack or cardiac arrest.
The effectiveness of defibrillation decreases significantly after a cardiac arrest, but it can still be successful if applied within 5 to 10 minutes. The chance of survival and recovery diminishes rapidly as time passes without intervention. Factors such as the underlying cause of the arrest, the patient's health, and the quality of CPR provided also play a crucial role in outcomes. Prompt medical response is essential for maximizing the chances of successful defibrillation.
Michael Jackson went into respiratory arrest from an overdose given him by a physician. When a person goes into respiratory arrest, it leads to a cardiac arrest, meaning, the heart stops beating. Michael Jackson died from a combination of cardio-pulmonary arrest since his physician was not present in the room, so no CPR was started until M.J. was already dead.
