Modern AEDs Require Little Training

Thursday, May 26th, 2011

Defibrillation is the process of delivering electrical currents to the heart of a person with a life threatening cardiac emergency, such as cardiac arrhythmias, ventricular fibrillation, and pulseless ventricular tachycardia. Every minute without defibrillation decreases the victim’s chance for survival by 10 percent. The Automated Electronic Defibrillator or AED automatically diagnoses a life threatening cardiac emergency, and delivers electrical currents to the victim as needed.

AEDs are extremely easy for most people to use. When the machine is turned on, it will instruct the user on what to do. No one should be touching the patient during the defibrillation process, as this could cause a false reading. If a shock is warranted, the battery will charge in preparation to deliver a shock. The AED guides the user through each step of this process. Depending on the model, the AED may instruct the user to give CPR as needed.

AEDs require minimal training to use, automatically analyzing the cardiac victim’s heart rhythm and determining whether a shock is required. The AED will administer a shock without the user’s command. In most circumstances, the user cannot override an AED’s “no shock” advisory.

All AEDs approved in the United States now come with an electric voice prompt to guide users through each step. Some users may be hearing impaired, so there are AED models that have visual prompts as well. Most of these units have been designed by non-medical operators.

In CPR training through The Red Cross, there is now a section focusing on the use of AEDs. The whole section takes no more than 10 minutes to review, but gives the trainees confidence in knowing that if they needed to use an AED in public, it would not be a complicated procedure. This ensures the survival of many people out in the community. In fact, AEDs are giving rise to the idea of PADs (public access device), which experts are agreeing has the potential to be the single greatest advancement in the treatment of out-of-hospital cardiac emergencies since CPR.

The first commercially available AEDs gave a high energy shock of 360-400 joules, depending on the model. This increased cardiac injury and sometimes caused third degree burns to the cardiac victim. Today, AEDs give two lower energy shocks off 120-200 joules, with each shock moving in opposite polarities between pads. This has proven more effective, and reduces the risk of cardiac injury, as well as reducing patient recovery time.

The fact that the general public does not have to determine the electrical energy output, or determine the steps to take in using an AED, makes public confidence rise. The likelihood of a person in the public using an AED to help a victim of a cardiac emergency is much more plausible. This, in turn will save many lives.

Why Cardiac Arrest Survival Odds are Better in Public Places

Tuesday, May 24th, 2011

Cardiac arrest is when the heart ceases to function. A heart attack, which is the blockage of a vessel supplying a heart muscle, can cause the heart to stop. But nearly 80% of cardiac arrests are not caused by a heart attack. Instead, they are what EMT’s call “shockable arrests.” That is when the heart’s electrical signals have gone haywire, but can be reset by the delivery of a powerful electric shock. Most people die within minutes from cardiac arrest; the survival rate is an abysmal eight percent. But an individual’s chance to recover is significantly higher if the arrest occurs in public. That’s because people trained in CPR, meaning cardiopulmonary resuscitation, are more likely to be around. Better yet the little machine designed to provide that critical electric shock could be nearby, too. Minutes and even seconds are critical in rescuing somebody from cardiac arrest.

“Shockable Arrests”

Electrical signals from the brain tell the heart when to beat. Similar to the action of a timing belt, these signals control which parts of the heart does its job and when. For a variety of reasons, the heart goes into what’s called ventricular tachycardia or VT. This is when the heart goes into hyper-drive, beating from 120 to over 200 times a minute. A normal heart rate at rest is 60 to 80 beats per minute. The lower heart chambers, or ventricles, begin to beat blood out faster than they can fill. If VT continues, the heart can then advance to deadly VF, or ventricle fibrillation. VF is when the ventricles can only twitch uselessly, stopping the blood flow to the brain. This is the point of no return. Unless electric shock is applied within less than five minutes, asystole, better known as flat line, follows. Usually after then even electric shock has no effect because the heart has died. If cardiac arrest happens at home, chances are slim that machine and those trained people are available.

Automated External Defibrillator

That little machine is a godsend to people who have gone into VF. Designed to be used by anybody able to follow a few brief directions, the automated external defibrillator, or AED, delivers that critical shock to restore normal rhythm. Leads are simply and easily attached to the chest. They then inform the machine if indeed the heart has arrested and it it’s because of VF. If it determines the need for shock it can be delivered immediately. The shock actually stops the heart completely. It then rests momentarily before it hopefully resumes beating at a more normal rhythm. The AED can confirm this.

These life-saving machines are found in more and more locations every day. They’re in many places; airports, office buildings, restaurants, courthouses, schools and even bars are stocking them. There’s good reason for this. More than a third of people who suffer cardiac arrest in public and treated with an AED survived. That’s much better odds than the national average of only eight percent.

Defibrillators in Public Places Increase Survival Rates

Thursday, May 19th, 2011

Many years ago, if a person had a heart attack and was in a public place, the results could be devastating if emergency medical treatment was not provided in time. Whether the person would make it or not was simply a coin toss up, depending on how severe the heart attack was.

Luckily, many public places now have portable defibrillators available in case of a medical emergency. This has drastically decreased the number of deaths that occur in public places. Malls, community centers, airports, and other large places where large numbers of people pass through are now making defibrillators available for public use. Finding a defibrillator in a public place is now as common as finding a fire extinguisher.

Automatic External Defibrillators have long been used by medical professionals to shock a person’s heart and re-set the heart rhythm back to a normal rate. Commonly referred to as AEDs, defibrillators are portable devices that deliver a shock to the heart, and are made to recognize abnormal heart rhythms.

Receiving training and certification to use a defibrillator is easy to obtain, and the American Heart Association offers training along with CPR certification. Using a defibrillator is actually easier than performing CPR, so medical experts as well as the American Heart Association actually recommend that people use a defibrillator before trying CPR. Performing CPR can immediately help regain a normal blood pressure and flow, but it’s even more important to restore a normal heart rate through the use of a defibrillator. Since these are so easy to use, it is extremely wise for public places to carry a defibrillator. Not only are they simple to use and lightweight, they also have extremely high success rates.

Now commonly found in public places, the average person can now save a life in places like schools, malls, and airports. Almost anyone can operate a defibrillator, as all it requires is that you turn it on by moving the lid, and then follow the voice instructions that come directly from the defibrillator. Each step is instructed by the defibrillator, telling the person what to do, including when it is time to stop and start CPR. In the event of a medical emergency, one should always call 9-1-1, but using a defibrillator can help save a life while waiting on medical responders to arrive.

The American Heart Association states that 294,851 of 9-1-1 calls are made each year for cardiac arrest. If more people know how to use a defibrillator, they could be saving a life. A person who is experiencing some sort of heart failure has a better chance of surviving when they are revived within the first four minutes, meaning that having access to a defibrillator in a public place increases the chance of survival more than anything else that could be done.

Although medical responders try to reach medical emergencies quickly, public places that carry portable defibrillators are helping to insure that a life has a better chance of being saved.

Recovering From a Heart Attack

Tuesday, May 17th, 2011

Recovering from a heart attack may take two or three months. You may only be in the hospital for a week, perhaps even less, but it may take a while before you can return to all the activities you were involved with before your attack.

Many hospitals and other medical facilities will provide rehabilitation programs to help educate you on steps you need to take in recovering from your heart attack. The chances of a future attack for some are lessened by a third by implanting a pager-sized defibrillator which will check for abnormal beats and zap the heart back to normal if necessary. Former Vice President Dick Cheney has had just such a defibrillator in him.

The cardiac rehabilitation programs provide exercise programs to many heart attack victims to aid in recovery and prevent future attacks. The programs will also show you how to lessen the stress in your life, teach you how to recognize if you might need further treatments, the proper diet for you, about sexual activity, and additional issues a heart attack victim might face. Such programs may also give you the chance to talk about with other heart attack victims about what you are feeling and how your life has been affected.

All of these issues will be important in your recovering from a heart attack. How long your personal recovery will take will depend on what your daily activities were previously, how severe your attack was, and how your body has responded. Keeping stress out of your life will quicken the pace of your recovery from the heart attack. Avoiding extremely hot or cold temperatures will hasten your recovery as well.

Doctors say heart attack victims need to take a look at their lives. Of course, smokers should quit smoking. It is important to begin an exercise program recommended by your doctor. You may have to make changes to your diet. Some people may even need to consider whether they need to make changes in their jobs. You will need to take all medications you doctor has recommended at the prescribed times. If changes are not made, there will be a greater chance of a future attack.

Additional procedures may be necessary to avoid future attacks. These can include additional medications you are not yet taking, bypass surgery, and percutaneous coronary interventions.

The use of a defibrillator may also lessen your chances of another heart attack. While 250,000 people have a heart attack annually while not in a hospital, and more than 90 percent of such people die, a defibrillator may prevent many such deaths. Some doctors estimate two to three million people could be helped by a defibrillator.

While a defibrillator may cost $20,000, and the total cost of a night’s hospital stay, surgery to install the device, and receiving a defibrillator can cost $40,000 to $60,000, higher demand could drive costs down.

The good news is, if you have had a heart attack, there are things that can be done to prevent another one.

The Importance of Defibrillators in Public Places

Thursday, May 12th, 2011

A defibrillator is a valuable device to have around when there’s an emergency situation, such as a person’s having cardiac arrest, or when their heart stops and it is not receiving enough oxygen, which in many cases have proved to be fatal.

A defibrillator is a device that is designed to “jumpstart” a person’s heart when it has suddenly stopped functioning properly. Another name for a defibrillator is an AED, which stands for Automated External Defibrillator. At one time, because most people didn’t have enough knowledge on how to come to the aid of a person’s suffering from cardiac arrest, defibrillators weren’t as commonplace as they are becoming today, but because of the rise of heart-related fatalities in recent decades, the presence of defibrillators in public places are becoming increasingly common.

The importance of having defibrillators in public places is just as important as having fire alarms in public places. Just imagine a school or an office building having no fire alarms. Then how are people going to know whether or not to evacuate a potential danger situation? That’s the purpose of having defibrillators.

Because we live in an unpredictable world in which anything can happen at any given moment, it’s always good to be prepared. As the old adage goes, ‘to be forewarned is to be forearmed’. The same applies in having a defibrillator in a public place.

Happily, the presence of defibrillators in public places is now rapidly beginning to catch on. In many places, wherever’s there’s a fire alarm, there’s a defibrillator right next to it. Also like a fire alarm, it has written instruction on how to properly use a defibrillator in the event of an emergency.

Yes, defibrillators are finally becoming part of the social consciousness of society today. This is not just true in America, but throughout the world as a whole. People get sick everywhere, so they want to have access to the same safety facilities as Americans do.

Sometimes-unfortunately-this may affect us in a personal way. One day, one of our loved ones or we may appreciate the value of having a defibrillator by our side. This is something that has been hit close to home for some.

So, there’s no reason to be surprised if we should see such a device in our school, office building, or even our local restaurant. Unfortunate situations happen everywhere, and it’s better to have such defibrillators right there on the premises than to have to wait for an ambulance, which can take who knows how long, and when they arrive, it may be too late.

Yes, defibrillators have finally become a common staple of many institutions, it is being taken seriously by many people, who perhaps formerly did not appreciate its value-until something happened to them or someone that they love-or loved.

Never underestimate the importance of having a defibrillator around. It can truly be a lifesaver, just as it already has to numerous people, who can testify as to its effectiveness. By all means, always appreciate the importance of having defibrillators in public places.

Sudden Cardiac Arrest: What You Can Do to Help

Monday, May 2nd, 2011

Heart attacks or cardiac arrest are killers. These killers are often silent and appear with little to no warning. The heart muscle is a unique muscle of the body. The skeletal muscles need direct impulses from the nervous system in order to perform the required duty. The smooth muscles of the body, the ones responsible for breathing and digesting foods, also need impulses from the body. The heart does not need any outside source to tell it when and how to beat. This is the definition for automaticity. The heart has pacemaker cells which work in unison with each other to ensure the complete filling and expulsion of blood with each heartbeat. The heart will beat on its own over 40 million times a year. This is until something convinces the heart to stop working. Poor diet, genetics, cigarette smoking are just a few outside elements which can help to weaken the heart. Even the high energy drinks which make your heart race can cause the heart to enlarge just like a body builders muscles get bigger with each work out. This takes away from the needed elasticity of the heart muscle. When any portion of the heart is outside of normal conditions it threatens the life of the person it is in.

Contrary to television, a flat line, asystole, isn’t when you deliver an electrical shock. Ventricular Fibrillation, the most common rhythm of a cardiac insult, and Ventricular Tachycardia are the only two conditions the heart can tolerate and benefit from an external electrical push. Electricity is needed during these times to help “re-set’ the automatic conduction cells of the heart, preferably the Sino-Atrial Node. External defibrillators are the only device approved for this emergency.

Many different companies make various styles of these important machines. It does not matter the make or the model, all of them are equally important during a cardiac arrest. AED’s or defibrillators are fool proof. Turn them on and they will tell you what to do each step of the way. This is probably the most critical event to happen during an arrest, CPR is not as important as the delivery of the electricity, as long as the defibrillator tells you “shock advised”. Defibrillation’s the one event which may take a quivering heart out of one of the two fatal rhythms. CPR buys time for the defibrillator to arrive and to be attached to the victim.

In a simplistic explanation of what an AED or defibrillator will do is as follows:
After ensuring you are safe and the patient is not wet, turn the device on, some power up once the case has been opened. The defibrillator will tell you to attach pads, then to press analyze. Once a rhythm has been identified it will tell you “shock advised” or “continue CPR.” Make sure no one is touching the victim when you press “analyze” or “shock,” defibrillators will interpret the rhythm incorrectly and will deliver a shock to the person touching the victim.

Cardiac Arrest: Three Steps to Recovery

Friday, April 29th, 2011

Cardiac arrest can be described as a sudden decrease or complete cessation of cardiac function. In other words, the heart stops beating or stops beating effectively and efficiently, and causes a decrease or complete loss of circulation, which then leads to decreased or arrested breathing. Cardiac arrest can, and often does lead to death because every minute that passes affects the eventual outcome for that person. However, there are several things a bystander can do, specifically three important steps that can be taken when someone has gone into cardiac arrest.

The first step is to begin administering CPR as quickly as possible. CPR stands for cardiopulmonary resuscitation and it is the artificial breathing for another person while simultaneously performing chest compressions to pump the heart manually. To begin administering CPR, roll the person onto their back. Next raise the chin and be sure their airway is clear. If the airway is blocked use a finger to swipe any obstruction from the back of the throat and be sure to pull the tongue forward as to ensure it does not become an obstruction. Then begin mouth-to-mouth resuscitation by manually blowing air into the affected person’s mouth and observing that the lungs inflate and the chest expands.

The second aspect to CPR is chest compression that is performed by placing two hands, one on top of the other, in the center of the person’s chest and pushing down swiftly and firmly for a succession of at least five compressions. This will manually force the heart to pump and therefore create an artificial form of circulation to ensure blood is flowing to the person’s lungs and brain. While someone is performing CPR it is best to call 9-1-1 or the local emergency response center, as well as obtain an automated external defibrillator, or AED. While CPR is helpful and useful, an AED has been proven capable of turning an irregular heartbeat into a normal beat.

The AED functions by delivering an electrical shock to the heart muscle. Recently AED machines have been manufactured in a compact version and can be found in most public settings. They are easy to use and all have instructions on how to properly administer treatment. An automated external defibrillator has computerized instructions that will give step by step instructions to the user once turned on, and also supplies diagrams to show exactly where to place the pads and if a shock is needed to restore normal heart function. The AED also does an automatic evaluation of the affected person’s heart rate in the form of an EKG, or an electrocardiogram. If a shock is needed to restore normal cardiac rhythm the machine will instruct the user on exactly what steps to take to administer a shock, and will then immediately continue with EKG tracking to determine the effectiveness of the shock. It is important to take these steps immediately when someone is in cardiac arrest as life or death outcomes can be determined within minutes of its onset.

Simple Steps to Saving a Life with AED

Monday, April 25th, 2011

The steps to saving a life with an automated external defibrillator (AED) are safe and simple to follow. When a person is undergoing a cardiac arrest, the first five minutes are the most important because if nothing is done within this short period of time, the patient will succumb to death. The first step is to make sure that there are at least two people so that one will call 911 and the other will retrieve the AED. If there is only one person, the first step is to call for emergency response team, then fetch the AED and later check if the patient is breathing.

Performing CPR is simple when AED is readily available. A person needs to check if the patient is still breathing. Most cases, the patient will have difficulties while breathing and they will fall down. Positioning a person for CPR is very easy because you want to put the device on the patient’s chest. This means that the patient should be positioned to lie on her back. The head should be tilted back and chin rose to check for breathing. This check should not exceed 10 seconds because time is an important factor. If the patient on the floor is not breathing, two rescue breaths should be administered. Signs of blood circulation should be checked before attaching the AED. When there no signs, it means that the heart is slowly failing. The AED should be turned on and audio commands followed. The most amazing thing about this device is that it does not require very technical skills to operate it. The audio command does everything and the device first analyzes the heart for a slight pulse which can be shocked.

The device has two pads that should be attached on the patient’s chest. One pad is attached on the right chest upper side while the other one is attached on the lower left side. These pads need to be dry and this means water or sweat needs to be wiped off the patient’s chest before attaching the pads. The pads are labeled and this shows a person where they should be attached. There is a wire that goes to the AED from the two pads. These wires should be attached to the AED for the defibrillator to work.

One of the most important things to note when operating the AED is that nobody should touch the patient while the AED is on. This means that when the device starts to analyze for a pulse, other people near the patient should clear off because the AED will be incorrect and analyze others pulses. The ‘Analyze’ button is clearly labeled and this should be pressed for the AED to automatically start its analysis. The analysis will be complete after a short time and then the audio command will ask for a shock. The shock button should be pressed and then let the AED reanalyze again. This will help save a life and if the patient is not breathing, rescue breaths should be administered until the chest raises and then allow the AED to reanalyze. Once the patient is breathing easily, she should be placed in a resting position and wait for the emergency personnel.

Manual vs. Automated AEDs

Wednesday, April 20th, 2011

What is an AED? It stands for Automatic External Defibrillator. Maybe you haven’t thought about using one lately, but knowing more about them may save someone’s life. Defibrillators are used to save lives of people that have had their heart stop or dangerous arrhythmias. You probably think of them being used only in a hospital or by EMTs, but many work places and homes are keeping them close by too.

There are two kinds of Defibrillators. The first is a manual defibrillator. The manual defibrillator is used together with an electrocardiogram device which doctors and technicians use to make a diagnosis. The diagnosis will determine the cardiac condition. These are the traditional “paddles” you see used in a lot of movies. The paddles are used by doctors and EMTs to shock the patient’s heart back to beating again. They’ve been used successfully for years. However, only a trained physician or technician can use them. You have to have training and experience to use manual defibrillators.

The second kind of defibrillator is the Automated External Defibrillator. This is a small electronic unit that is portable. It’s used when someone has had cardiac arrest has or is dangerously close to cardiac arrest occurring. The health professionals are using these more and more because they are so advanced. The difference between this device and the manual defibrillator is that the automated external defibrillator is meant for the ordinary person to use. Even though ordinary people can use them health professionals use them too. They offer the ability to monitor the patient’s conditions and because they are computerized data can be recorded and stored instantly. The professional can instantly see the rhythm of the patient’s heart during CPR as well. So CPR can be stopped when the AED lets the professional know automatically.

What happens when someone’s heart stops in a restaurant, mall or school? If an emergency medical team can’t get there fast enough what can be done? This is why Automated External Defibrillators have become so popular. Restaurants, malls, businesses and homes are investing in this modern device to save lives. Yes anyone can buy an Automated External Defibrillator but it’s important to know about Good Samaritan laws in your state. Each state has different views about helping someone that is injured. It’s a good idea to check your state and laws especially if you have a business. Although the Automated External Defibrillator is widely available, training is strongly advised.

Both the Manual and Automated External Defibrillator use electrical charges or current to stimulate muscular contraction of the heart. Both are used today by doctors and emergency technicians. There’s no doubt though that the Automated External Defibrillator has brought lifesaving hope to many people who otherwise may have died.

Benefits of an Implantable Cardioverter-Defibrillator

Monday, April 18th, 2011

Individuals who have heart failure occasionally can have a heart rhythm that is abnormal and this can lead to a heart attack and even death. This means in cases where an individual heart stops, unless immediate intervention is made and the rhythm is restored to normal, they will die. An implantable cardioverter defibrillator works by giving the heart a shock in order to restore the normal heart rhythm. This device is placed in those who survived and abnormal rhythm that may cause a sudden death.

The implantable cardioverter defibrillator also referred to as ICD transformed the treatment for patients who are at risk of sudden cardiac arrest. This device was first introduced in 1980 to humans and has developed from a last resort form of treatment to a prophylactic therapy and first line treatment for those at risk for ventricular fibrillation or ventricular tachycardia.

ICD Benefits

The ICD minimizes the risk of provident therapies that are inadequate. The defibrillator checks the correctness of treatment play, classification, episode detection, and IEGM also known as intracardiac electrogram. These devices have to–date provided life saving benefits. Researchers in the cardiac psychology field have stated that an ICD patient’s QoL is equal or better than individuals who take medications that are anti-arrhythmic

Patients who have a defibrillator can perform Just about all types of physical activities. A patient can enjoy all types of sports where there is not risk of damage to the ICD.

Some clinical trials have indicated the significant superiority of the defibrillator over anti arrhythmic drugs for the prevention of malignant arrhythmia death. A trial done in 2005 showed a great morality benefit that was “all-cause” in patients that had defibrillators. Patients that had congestive heart failure and implanted with a defibrillator experience 23 percent less all cause death risk than individuals in the placebo group and a significant reduction in morality of 7.2% points following 5 years in the complete population. A trial done in 1999, consisting of 1,016 patients resulted in those that received AAD treatments having more deaths than individuals with implantable cardioverter defibrillators. In a trial done in 2002, there was benefit within the implantable cardioverter defibrillator patients that had experience myocardial infarction combined with decreased left ventricular function.

Defibrillators were initially implanted through thoracotomy where defibrillator patches were applied to the pericardium or epicardium. Nowadays, most ICDs are transvenously implanted, placed similar to pacemakers in the left pectoral. As technology has advanced, these devices have become less invasive and smaller. Current defibrillators are around 12.9 millimeters thick and weigh 70 grams.

Defibrillators and Women

A recent study has indicated that women who have ICDs do extremely well with this device. This device was once kept for patients who had the worst cases of heart failure. Currently women who receive this type of therapy experienced a 70 percent decrease in the events of heart failure and 72 percent decreased risk of dying from related causes.
