What are the different parts of a defibrillator?

What are the different parts of a defibrillator?

3 main parts: Generally speaking: 1) the lead that sits in the heart to detect electrical signals from heart muscle, and to conduct electrical shocks from the device (if needed); 2) the small unit in the chest wall containing the computer which interprets the incoming electrical signals from the heart (via the lead) and gives pre-programmed therapies; 3) the battery that the computer runs on (also in this unit). ...Read more

How are defibrillators used in the body?

ICD: Icds are implanted to monitor the electrical activity of very abnormal hearts to see if a life threatening rhythm occurs. If it detects one of these rhythms, it will charge its capacitor and fire a shock to defibrillate the heart back to stable rhythm. In appropriate patients these devices save lives. ...Read more

What is a defibrillator?

What is a defibrillator?

Device for the heart: A defibrillator uses electrical current to reset the rhythm of the heart when it is irregular and too rapid. They are used in cardiac arrest when the rhythm is ventricular fibrillation or tachycardia. They can be used to reset atrial fibrillation either emergently or electively as well. They can be external devices or can even be implanted in the body for patients at risk of arrhythmias. ...Read more

How can you use a defibrillator?

How can you use a defibrillator?

Variety of ways: There are two kinds of defibrillators, internal and external. Internal defibrillators are implanted under the skin similar to a permanent pacemaker. This type of defibrillator works automatically and does not require human intervention. External defibrillators are found in hospitals and in public areas. These are manually applied to the outside of the chest. ...Read more

How does a defibrillator function?

How does a defibrillator function?

Electrical system: A defibrillator causes all myocardial (heart) cells to become depolarized at the same time. This extinguishes the abnormal arrhythmia, and allows the natural cardiac pacemaker to kick back in. This requires a large electrical current, to make sure all myocardial cells get activated at the same time. ...Read more

Why would a defibrillator not work?

Debirillator: A defibrillator is an electric device and subject to all the failure modes of any electric device. Assuming the device has a good power source and all components are working and it delivers the shock appropriately, there is no guarantee the heart will respond. If the cardiac status is too far gone electrophysiologically the rhythm won't convert. ...Read more

How is a defibrillator made to work?

How is a defibrillator made to work?

Defibrillator: Defibrillaor's function is to sense a life sensing rhythm and quickly deliver a life-saving shock. It contains a sensor (consisting of electronic filters/amplifiers). It also contains a 3v battery that is quickly charged upto 750 volts with help of a transformer in matter of 5-15 seconds. A high voltage capacitor stores the charge that is then delivered to the heart to shock the heart. ...Read more

How did the defibrillator get named?

How did the defibrillator get named?

What it does: A defibrillator provides an electrical current that is measured in joules (a measure of electrical energy). This electrical energy is used to "shock" the heart back into a normal rhythm from a terminal rhythm such as ventricular fibrillation. Thus the mechanism by which the device accomplished this is to "de" fibrillate a heart; hence defibrillator. ...Read more

When does someone use a defibrillator?

To stop fibrillation: "fibrillation" is when the heart muscle is not contracting efficiently, but rather twitching weakly at rapid rates. If this involves the bottom chambers of the heart ("ventricles"), it is life threatening as normal cardiac output falls drastically. The rhythm must be normalized quickly to resume normal heart output, and electrical shocks promptly defibrillate, i.e. Stop the abnormal rhythm. ...Read more

Would a tazer work as a defibrillator?

No, but…: A taser cannot function as a defibrillator (the energies it utilizes are too low). It is a point of great medical and legal contention whether electronic control devices can in fact cause fibrillation, and the company taser has taken numerous legal actions in an effort to maintain medicolegal consensus that they cannot. I'll leave the matter at that. ...Read more

Where can someone find a defibrillator?

Many public place: An external defibrillator can be found in many public places, thanks to recent studies showing that availability of these automated devices can be used by even untrained bystanders to save lives during a cardiac arrest. Airports usually have them displayed on a wall, as do many theaters, concert halls, etc. Restaurants may have one as well but you probably have to ask someone to go get it. ...Read more

Should everyone buy a defibrillator for their home?

Should everyone buy a defibrillator for their home?

Nice, not necessary: An automatic external defibriillator (AED) is important for cardiac arrest situations, however it is not practical for every home to have one unless you or your family members are at increased risk. Aeds cost about $1000-$1200, battery needs to be replaced every 5 years ($90-$110) and the pads (adult & pediatric) need to be replaced every 18-24 months ($100 each). ...Read more

Can a defibrillator be removed from inside the body?

Yes: A defibrillator is a pacemaker device that also is able to deliver an electric shock to the heart for life threatening rhythm disturbances. It is connected to the heart via leads that go into the heart vy the veins or can be implanted surgically on the outside of the heart. The device is placed under the skin and can be removed. Leads can also be removed but that is more difficult. ...Read more

What is the expected value of owning a defibrillator?

None: I assume you're referring to an AED - automatic external defibrillator. Unless you live in a cardiac care unit, an airport, or some other large public area, you'll pay a lot of money and never use it. It won't benefit YOU since someone else has to apply it. It must be tested and certified annually (another expense). (If you're talking about an INTERNAL defibrillator, disregard all of the above) ...Read more

What amount shocks does it usually take for defibrillator to work?

What amount shocks does it usually take for defibrillator to work?

Usually One: The goal with defibrillator therapy is to minimize shocks. Most internal defibrillators are programmed with a high enough energy that they will often but not always be effective on the first shock. There are many variables to consider however and the data for external defibrillators (AED's) is different. ...Read more

Defibrillators are often mistaken for being responsible for reviving a person. But, what can revive a person after they have died or "flatlined"?

CPR: Defibrillators will revive a cardiac arrest due to a disorganized rhythm called ventricular fibrillation but not in the absence of any rhythm or as you call it flat line which is the other mechanism of cardiac arrest. The latter is often treated with drugs such as epinephrine or a temporary pacemaker. But the initial management of both consists of chest compressions (CPR) until definite treatmen. ...Read more

Would paramedics attach a defibrillator pads on someone found asystolic?

Likely yes: The pads can help determine the heart rhythm, functioning as diagnostic leads on most machines, so are quicker than waiting to get the 3 or 5 regular leads on. Pads are commonly applied to persons with unstable heart rhythms / palpitations / some with chest pains / unresponsive patients. ...Read more

Do defibrillators work?

Oh yes: Defibrillators are extraordinarily effective devices for the treatment of what would otherwise be fatal lower chamber heart rhythms. That said, they must be used in an extremely timely fashion or their benefits will not prevent irreversible damage from the lack of blood flow seen in these dangerous rhythms. ...Read more

What types of defibrillators are there?

Internal & external: Implantable (internal) defibrillators remain in the body, whereas external defibrillators are the boxes with paddles that you see on tv shows. They both shock the heart out of life-threatening cardiac arrest rhythm if need be. There are automated external units that lay people can use; you put paddles on person's chest and the machine determines the rhythm and speaks commands to give a shock. ...Read more
