Biphasic defibrillation was introduced after the traditional heart defibrillators were released, which are monophasic. These two devices are used to bring a heart back to normal rhythm after going into cardiac arrest. There was a lot of hype about the biphasic defibrillators being so much better and that so many more lives were going to be saved with these devices. However, these two different devices are serving the same purpose and are equivalent.

A monophasic defibrillator sends a single shock into the body in one direction. This charge only goes in one direction. The biphasic defibrillator sends half of a shock into the body in one direction and the other half of the charge in the opposite direction. This defibrillator alternates directions in about 10 milliseconds, which is considered to be a cycle. Even though they send shock waves differently throughout the body, they work the same, and neither device has proven to work better in saving people at all. They both have the same results in defibrillation.

Although, there are advantages of the biphasic defibrillator. The biphasic defibrillator was made smaller than the monophasic device, which makes it much more portable. The biphasic is also cheaper and cost less than the monophasic. The biggest advantage that the biphasic defibrillator has over the monophasic is that the batteries last longer and that it takes less energy to zap the patients than it does with a monophasic. This has been a good enough reason for many doctors to switch over is in the energy.

Biphasic defibrillation acts differently as monophasic defibrillation because the two devices send shock waves through the body in different ways. Both of the devices are intended to save an individual when in cardiac arrest to provide immediate care restoring the heart back to a normal beat. Both of these devices work the same and neither device is better or saves heart attack patients more. The two devices are equivalent. Although, the biphasic defibrillator is cheaper, smaller, and saves energy. These are the biggest reasons the biphasic is a preferred defibrillator, but not because of the way the currents are sent through the body.

How does a defibrillator work and how would it help if my dad had a heart attack? The importance is critical and can mean life or death. The amount of time you start defibrillation can be crucial to full recovery.

The heart works by pumping blood throughout the body. It performs fluttering to do this. It is also known as fibrillation. When someone goes into cardiac arrest, his or her heart may be erratically beating and abnormal. A defibrillator, when used on someone in cardiac arrest, actually stops the heart for a moment. The pace making cells in the heart then have a chance to regain a normal heart rhythm. Some people say it jolts the heart back into a normal heartbeat. However, it sends an electrical shock, which must be delivered in order to restore a normal heartbeat.

A defibrillator doesn’t work if a person is in flat line. A flat line means the person’s heart has stopped altogether. Since a defibrillator stops the heart, it wouldn’t make sense to stop a heart that is already stopped. Some say that a flat line can be a very weak heartbeat or fibrillating so they like to try the defibrillators. Other doctors believe that CPR is most important to be used when a person is at a flat line. CPR is known to improve the oxygenation of the heart, which it needs to begin beating again.

Once a person goes into cardiac arrest, the sooner defibrillation begins the better chance they have of surviving. Defibrillation should occur immediately. The more time that passes, increases the chances of not being able to restore the heart to a normal heartbeat. If 10 minutes pass before defibrillation treatment can be done, the chances are slim of a full recovery of the patient. Time is critical.

Today there are many types of defibrillators. There are implantable devices that are defibrillators that can be surgically put inside the body. There are external and automated defibrillators also. The defibrillator work on a heart and the shock wave it sends through someone’s heart to restore a normal rhythm saves thousands of lives every year. These instruments are lifesavers.

Public access defibrillators (PAD) are automated external defibrillators (AED) that can be used by laymen and don’t need any expert medical worker when exigencies emerge. Sudden cardiac arrest causes blood clotting in the heart and death appears imminent wanting proper blood circulation in the body. Unable to get cardiopulmonary resuscitation, patient may die within a few minutes. But an electric shock to the heart generated by an automated external defibrillator by public access defibrillators may save life.

Defibrillation is a self-regulating clairvoyant of survival for patients with cardiac arrests not approachable to the hospital. It reduces the fatal time gap between the ambulance response time and emergency call using bystander cardiopulmonary resuscitation through public access defibrillators. Use of portable public access defibrillators by non-emergency workers giving respite to cardiac patients away from hospitals has led to dramatic increase in their survival rates. As reported at the American Heart Association’s Scientific Sessions 2003 the patient survival rate is 50% more for public access defibrillators administered patients.

Public access defibrillators include detectors, controllers and therapy delivery circuits. The detector diagnoses and informs ahead of a life threatening condition of a cardiac patient where as the controller instructs the defibrillator to automatically alert the therapy delivery circuit to provide immediate and proper therapy. Public access defibrillators are easy to use and can be appended to a patient by any attendant or bystander. Once appended the instrument adapts itself to monitor and administered the therapy automatically incase of life threatening condition of cardiac patients.

Public access defibrillators are known to save thousands of lives in the UK and US. Sudden cardiac arrest causes patients suffer from asystole and pulseless electrical activity due to lack of immediate defibrillating. It may affect a protracted interval of early ventricular fibrillation or the occurrence of permanent cardiac damage. Therefore, intervention by public access defibrillators to lessen defibrillation time increases the hope of patients’ survival. Seeing the importance of public access defibrillators, an Australian airline has decided to mount them in their aircrafts.

Using public access defibrillators is as simple as utilizing a fire extinguisher. No specialized training or any sort of medical knowledge is required to administer them to any patient. These devices also require minimal maintenance and could be continued with the help of telephone or interactive instruction. Their cost effectiveness is another succor to both the heart patients and the national and provincial governmental health care system. The targeted placement of public access defibrillators at places like airports and shopping malls is sure to be great help for a large number of susceptible people.

The efficacy and cost effectiveness of public access defibrillators in enhancing cardiac survival rate led to the increase in its installations in many cities. These devices are also being established at home by many rich businessmen for individual use. The growing use of public access defibrillators is a succor to hundreds of under privileged and retired cardiac patients living in areas far from ultra-modern hospitals.

The utility of defibrillators in improving the survival prospect of the patients suffering from cardiac arrest has resulted in dramatic increase in defibrillator sales. With considerable increase in heart diseases and large number of people falling prey to the cardiac arrest, defibrillators have become handy for many to survive the crucial time gap between the emergency call and arrival of the ambulance. The burgeoning installation of the device at public places and private homes as well as growing public awareness and acceptance are the main causes of the increase in number of defibrillators sold.

The jump in defibrillator sales has come at a time when cardiac arrest has seemingly become fatal. The race among private companies and shopping malls to install public access defibrillators also add to the increase in defibrillator sale. A reputed defibrillator makers has sold its automated external defibrillator version to about more than hundred fortune 500 and fortune 100 companies. The rising corporate responsibility to ensure the health and safety of its employees is certainly adding to the defibrillator sales.

Now a days, the public seems to be more aware of the use of defibrillators. Increasing government campaign through media, internet and public seminars on health to sensitize people on the use of defibrillators has led to the tremendous increase in the public interest for the device. Seeing the growing public notice of the device companies like Phillips are offering different versions of defibrillators at reasonable price for use at home. It helps the rising defibrillator sales.

Mass procurement of the device by the government health care system particularly in the US and Scotland is also a leading factor in rapid increase of defibrillator sales. Laws in many American states including Illinois, Pennsylvania, New York, and Rhode Island have made it mandatory for health clubs and big public schools to set up defibrillators has also a factor in increasing its sale. Even the local administration is ready to fund the purchasing and installation cost.

Burgeoning defibrillator sales have led to aggressive market campaign by many players in the segment. Philips and Medtronic, the largest manufacture of defibrillators are locked in a battle of keen contest. The consequent results like newer offers, cheaper rates, better consumer satisfaction and greater technological advancement have brought an greater than ever range of defibrillators in the market. The rising defibrillator sales have also led to the entry of new players to the market like Zoll, Cardiac Science and Panasonic.

Rising defibrillator sales are fueling growth of both the heart care technology and the medical industry. Above all, the cardiac patients are getting a better deal and now their survival rate is higher than the expected. Installation of public access defibrillators and growing awareness of the device is not only helps defibrillator sales, but also salvage millions of heart patients.

A defibrillator cabinet is personal protective equipment attached to every Automated External Defibrillator. Though expected to be used as a protective shield, the defibrillator cabinet also keeps the body fluids away from electric particles when the shock therapy is administered to the cardiac patients. Made of steel, it also adds to the shape and size of the AED.

Defibrillator cabinet is used as a storage facility for several equipments such as a microshield, trauma scissors, gloves for Personal Protection and a razor. The microshield is basically designed to discourage and deter any attempt to open the AED and safeguard the sophisticated equipments from any distortion. Trauma scissors known as tuff cuts, are used by paramedics and emergency medical staff to cut clothes off people with cardiac arrest to ensure better oxygen flow to the body. These scissors generally consist of a plastic handle suffused with a metal blade. The gloves need to be always worn to safeguard the body from shock radiation.

The defibrillator cabinet is generally fitted with an 85-decibel alarm with a pressure sensitive button. It operates on 9-volt batteries and needs replacement on every six months. Any attempt to open the door led to sounding of alarm to deter any theft. You can also connect the alarm to your internal locking system. The more sophisticated cabinets like basic, surface mounted and semi-recessed ones come with both audible and flashing alight alarms. The last two categories can be inserted in to a wall stencil for less obtrusive look.

Most of the cabinets are made of sturdy heavy-gauge steel. The shape and size depend on the storage facility provided to accommodate supplementary medical supplies. The first aid and protective wear unit inside the defibrillator cabinet includes a entire, solid die cast, chrome-plated handle with adjustable roller catch, AED decals, heavy-duty hinge and a clear acrylic door alarm. A general wall mounted cabinet is made of 20-gauge, cold-rolled steel and normally accepted as durable for its high gloss, white electrostatic powder coat finish.

A defibrillator cabinet needs changing in every six months for safety and health concerns. The growing use of defibrillators and increasing public awareness about the device is leading to the availability of numerous cabinets of high quality in the market. The consumer has now better options to buy catchy and flashy designed cabinets and get better price to their money.

The portable defibrillator has revolutionized the use of cardiac care world over. Saving patients suffering from cardiac arrest is no more within the exclusively domain of emergency rooms or intensive care units within the hospital premises. Portable defibrillator is a handy device in the hands of people to avert death blow inflicted by sudden cardiac arrest.

A portable defibrillator is specifically designed to ensure more adaptability of defibrillator. It is manufactured to fight cardiac arrest or heart attack caused by fibrillation or irregular heart beat and ensure no-blood clotting inside the heart. Easy to carry, the portable defibrillator shocks the cardiac arrested heart to return to normalcy stimulating a manageable rhythm. It channels an electric current into the heart via our body using electrodes or paddles positioned on the chest. As a result the heart muscles ripple and fibrillation in the heart stops.

Before the development of the portable defibrillator, the device was inside the exclusive premise of heart physicians, hospitals and emergency technicians. The colossal size and complicated user was only to be administered by trained professionals. But the inauguration of portable defibrillator has taken the device out of hospital or medical setting. Simple to use because of its smaller size and easier user manual, any one even a layman now can administer the device and save lives.

Portable defibrillators have also reduced the risk associated with regular use of the device by untrained people. The inbuilt automated regulator within the device decides whether the patient suffering from cardiac arrest does need an electric current inflow. It is even able to assess the required wattage or power intensity needed for defibrillation. Minimizing possible misuse, the inbuilt computer forbids the operator to go beyond the required stage.

The light weight and transportable adaptability of the portable defibrillator make it ideal for storage and employ at any public place such as school, gate community, airport and sporting venues. A person with little or no medical training can also administer the device. The latest portable defibrillator developed by Zoll is just the size of a laptop computer. Among other features it includes totally automated controls and instructions with accent prompts. It automatically detects the need for treatment and instructs step by step on the process to administer proper treatment. The voice prompts help laypersons like security guards and flight attendants to use the device effectively to hoard the cardiac arrested patients from death till the proper medical service is arrived.

Though, the debate on the benefits of a portable defibrillator in the home is still raging, we can’t deny the fact that the device is of vital importance to cardiac arrest victims remote from the hospital location. With almost a million American citizens falling victim to cardiovascular disease every year, portable defibrillator is the best chance to ensure survival on the face of sudden death. Easy to carry and administer the device, portable defibrillator can be carried on your tour and ensure your successful fight with cardiac arrest.

A defibrillator monitor helps in having greater control over any situation and ensure better reliability of the Automated External Defibrillators (AEDs). Through the defibrillator monitor you can keep an eye on the condition of the cardiac patient in the emergency admissions, operating theatre or intensive care unit. Even the critical event records are automatically stored and be recalled when required.

Defibrillator monitors ensure more effective and sound administration of the device. Its color coded and clearly specialized steps helps in overcoming all operating errors and saves time. Cardiac arrest happens suddenly and that too without any prior symptoms in most of the cases. It causes mal-functions in the pulse system due to fluctuation in the heart caused by ventricular fibrillation. But use of defibrillator within five minutes can save the patient on the face of imminent death.

A defibrillator monitor helps in instructing a person in the easy and efficient administration of the device without any delay. Flashing the pulse rhythm of the heart, it also instructs on screen about what wattage and time period required for medical therapy in case of cardiac arrest. Automated External Defibrillators fitted with monitors are also regarded more reliable and handy to use by the increasingly aware cardiac patients.

Automated External Defibrillators are generally regarded as difficult to use by many for the high mortal risk involved incase of cardiac patients. Even the equipment with highly technological innovation and sophisticated treatment forbid many to handle it. But with a monitor, the use becomes more uncomplicated and effective. Almost all the present third generation defibrillators boast of LCD monitors to magnetize the customers as well as ensure most potent use of the device.

Treatment by defibrillators can increase survival chance to more than 90 percent. A minute interruption in defibrillation may decrease the rate by 10 percent. Monitor defibrillators are therefore potent enough to add more chance to your survival. Its clear-cut instruction in both voice and onscreen display helps in better use of the device. Reading the screen any one may be an attendant or peon or office manager can administer the device and save lives.

Contrary to the public perception, a defibrillator monitor is not too big or complicated. They are also not too expensive. Their merit not only lies in perfect use up but also in better look and greater impact. Most of them look handier and smaller compare to the devices without the monitor.

Defibrillator training ensures the best possible response from the device while the shock therapy is being administered to the cardiac patient. Most of the medical equipment made to handle high priority situations like the cardiac arrest require effectively trained personnel for maximum efficiency. Contrary to public perception, any layman can be trained with minimal time and education to administer the defibrillator shock to save lives.

A defibrillator is to operate by medical and non- medical personnel when they are taught the proper use of an external defibrillator. Organizations like American Heart Association offers advanced cardiac life support defibrillator training courses to more than 250,000 annually. The US Red Cross also offers training courses to more than 8.5 million people in handling cardio-vascular disease related equipment. The main purpose behind defibrillator training is to give enough education to the trainees to respond to an emergency situation without delay.

Defibrillator training uses a low-stress and straightforward approach. The manufacturing companies also help consumers use their automated external defibrillators correctly. The training course includes latest standards and techniques to prepare for unexpected cardiac arrest episodes for in most situations. The manufactures provide an optional programming kit to the customers for better handling of the device and to ensure the proper use of it.

Defibrillator training courses are designed to educate the students about how to use an Automated External Defibrillators in a reliable way and administer effective medical therapy shocks to increase chances of survival. Most of the defibrillator training courses include detailed coaching on heart conditions, resuscitation, CPR protocols and use of Automated External Defibrillators.

However, proper defibrillator training is of no value unless the personnel work in realistic situations. To give proper education and ensure their through assimilation among the trained medicos, the latest version of the AED Trainer 2 is comes with 10 realistic training scenarios planned according to internationally recognized emergency responder programs. The optional trainer kits available with the products offer additional flexibility to design and configure three custom scenarios as per your requirement.

Internal defibrillators are small battery powered units that deliver an electrical impulse to someone who is experiencing sudden cardiac arrest due to ventricular defibrillation. Before you or your loved one has a defibrillator implanted, you should learn about the device and what it does. Learning about the unit, the procedure, and what you can expect afterward will help alleviate anxiety.

An internal defibrillator constantly monitors an individual’s heart rate for any abnormalities. If the heart rate exceeds a certain number, an electrical therapy is administered to correct this problem. Studies show that when a person is experiencing cardiac arrest, defibrillation in the first several minutes increases the chances of survival.

Most defibrillators today also monitor for other heart conditions as well as cardiac arrest. If the heart is beating too slowly, the defibrillator acts as a pacemaker. If the heart is beating too fast, the defibrillator may give the heart a short burst of extra beats, which often corrects the problem before defibrillation. If it does not work, than the defibrillator gives the higher shock commonly associated with this device.

In the beginning uses of this therapy, internal defibrillators were put into the body through a thoracotomy and the defibrillator patches were applied to the epicardium or the pericardium. Now, most of the internal defibrillators are implanted transvenously into the left pectoral region. This is a similar placement to a pacemaker.

New technology has made internal defibrillators smaller and more easily implanted. Most weigh around 70 grams and are less than 13 mm thick. You may be able to feel the box and the leads under your skin, but as the wound heals, you shouldn’t experience any discomfort from it.

Many people feel worried about going home after having the device implanted. You should ask your nurses and doctors about the device and what to expect if you have questions. Knowing as much as you can about what to expect will help you feel more comfortable with the device.

If the defibrillator gives your heart an electrical impulse, you will likely feel pain that lasts for a few seconds. Those near you may notice you move suddenly, but they are completely safe from the electric impulse.

If you feel as though your heart is beating too fast or you are feeling dizzy, sit or lie down on the ground. Contact your doctor as soon as possible so that you can have the device and your heart checked out. If you feel unwell after a shock or if the device is giving multiple shocks, call 9-1-1 for an ambulance as it will be necessary to determine what is happening.

Internal defibrillators have been shown to help individuals who are at high risk for sudden cardiac arrest. New technology is making the devices safer and more efficient. If you or someone you love is having one implanted, ask your doctor to explain the device, the procedure, and what you can expect after the surgery.

Getting information on defibrillators is very useful in this fast moving world, where threats of cardiac attacks have become really trivial. Defibrillator is the device used in treating the disturbing and uneven movement of the heartbeat normally caused by a heart attack or a variety of other serious illnesses. Therefore, a little information on defibrillator helps in averting heart problems.

How a Defibrillator Works

Gathering information on defibrillators is very simple thing. It uses direct current as to give unsynchronized countershocks to stop ventricular fibrillation. The produced countershocks converts uneven and disturbed heart rhythm in an organized even and affective ways. The system has been administered by pressing a small button on the defibrillator paddles placed at the chest wall. Putting on the pressure to the defibrillator paddles enforces lungs to bring out the air from the chest wall in order to bringing it closer in contact with the heart.

Types of Defibrillators

A defibrillator normalizes heart beat movements caused by a heart stroke or serious illnesses. Getting information on various kinds of defibrillators including Manual external defibrillator, Manual internal defibrillator, Automated external defibrillator (AED), Semi-automated external defibrillator, and Implantable Cardioverter-Defibrillator (ICD) can be helpful. A brief discription of each of them has been explained below.

Manual External Defibrillator

Manual External Defibrillator is a kind of defibrillator with an inbuilt electrocardiogram to detect the condition of the heart. On the basis of diagonis of the heart, clinicians decide the intensity of the voltages to be given to the patient. Normally, electric pressure has been given through the paddles on the chest of the patients. This kind of defibralitor is commonly used in hospitals or ambulances.

Manual Internal Defibrillator

Also used in normalizing the heart beats, Manual Internal Delibrillator is just like normal defilbrillator, where electric charge is usually pumped in by internal paddles in close or direct contact with the heart. Because of its intricate usage, these devices are mainly used in operating theatres, where the chest can be opened or being treated by a surgeon.

Automated External Defibrillator (AED)

Information on defbrillator has become a life-saving treatment for all heart patients. Automated External Defibrillator is used to identify the rhythm of the heart through a computer based setup. The system identifies the need for an electric shock or not. Aiming at the layman usage, the appratus has been designed in such a way so that a common man with little training can operate it. This kind of equipment is generally found in government offices, shopping centres and other public places.

Semi-Automated External Defibrillator

This device carries both the features of full-manuated as well as automated units of defibrillator. Equipped with the AED capabilities, this unit also has an ECG display and manual override in it. Due to its distinguish features, this device is generally used by paramedics and emergency medicine technicians.

Implantable Cardioverter-Defibrillator

As its name suggests, Implantable Cardioverter-Defbrillator is used as implants and helps in keeping a close watch on the patient’s heart beat rhythm and capable of administering the shocks automatically through its designed program.

Defibrillator has increasingly become an important medical device for people prone to cardiovascular diseases. Information on defibrillators is necessary not only for heart patients but for everyone else is interested in keeping his or her heart healthy and pounding happily.
