A defibrillator is a device that discharges a controlled electric shock to break an arrhythmia. Defibrillation is done in the case of arrhythmias, atrial fibrillation, atrial flutter, ventricular tachycardia.
Defibrillation success depends on the discharging of an appropriate current to obtain the depolarization of the myocardium, this thing being conditioned by the position of electrodes, transthoracic impedance, the volume of hman body and the energy of electrical shock.
The energy used to the first defibrillation in adults is of 200 J, in case of failure, the procedure is repeated once again, with 200 J, and the rest of shocks during resuscitation will be made with an energy of 360 J. There is no limit to the number of shocks that can be done.
Defibrillation should be performed in groups of three. Since the three shocks can be made quickly, is not necessary to stop the sequence to perform cardiac massage and ventilation. After the third shock, the device analyzes the heart rhythm again and it will check the pulse. If the rescuer does not identify the pulse, the resuscitation maneuvers will be continued.
A defibrillator is an electric device that is used to change an irregular heartbeat back to normal. However, they do not come without waring.
Defibrillators are now found in many public places. One may see them on the walls in large shopping centers such as malls, in sports arenas, and in other types of businesses. People who are trained in CPR are also being trained to use them.
The American Heart Association does not recommend that a defibrillator be used as the first line of correction with a victim. CPR has the benefits of moving oxygen rich blood to the heart while a defibrillator only acts as an electrical charge designed to get the heart to respond. Since blood carries oxygen to the brain, it is very important that procedures to move the blood through-out the body are first implemented. Therefore, it is imperative that one begin CPR before attempting the use of a defibrillator.
You should use a defribulator when the patient has an irregualar heartbeat. Using it as soon as possible will increses chances of survival. Use what ever resuscitation technology you have, if theres nothing just continue with CPR.
