How are defibrillators used in the body?

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

Defibrillator (Definition)

Defibrillation is a common treatment for life-threatening cardiac dysrhythmias, ventricular fibrillation, and pulseless ventricular tachycardia. Defibrillation consists of delivering a therapeutic dose of electrical energy to the affected heart with a ...Read more

What is a defibrillator?

Multiple types: External defibrillators are used on an emergency basis to convert life threatening rapid ventricular arrhythmias. These are also available in a wearable form called a life vest. There are also implantable defibrillators inserted in survivors of sudden death or those at risk of sudden death. ...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 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

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

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

What happens if your body rejects the defibrillator?

Rejection: A AICD is a metal encased device, rejection is not an issue. The body will encase the device with fibrous tissue. Rejection is an issue with body tissue and not a metal device. So be assured. ...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
