The defibrillator is the tool that allows the abnormal beat of the heart to return to normal heart rhythm. If the fibrillated or newly stopped heart is given electrical energy in shock; the heart is stimulated from the outside and contracts. To shock the heart with a defibrillator; the heart must be in ventricular flutter or fibrillation. It is used in the treatment of VF/VT type rhythm disorders in the heart.

AED – Automatic External Defibrillator device AED is small; portable; and capable of analyzing heart rhythm; and can electroshock to establish a normal rhythm that will allow circulation when necessary. AED is a device specially developed for first aiders and is used until paramedics can reach the scene. Early electroshock application; treatment for sudden cardiac arrest; can cause the heart to beat with a rhythm that can re-circulate and can be lifesaving. In developed countries; there is an obligation to have AED devices placed in areas with a high concentration of people; such as stadiums; shopping malls; airports; which are easily accessible. AED devices; which are right to be used by ACLS-certified persons under ideal conditions; can also be used successfully by untrained persons thanks to the instructions and voice guidance that come in if necessary.

Devices perform shock with biphasic waveform. The devices can be easily transported with both stationary and carrying arms. Devices can operate from at least 2-200

joule in manual; automatic; asynchronous; and synchronous modes.  The devices also have 12-channel ECG; SPO2; CO2 parameters as standard; the corresponding values are displayed numerically and graphically on the screen. The devices have a color display of at least 6 inches. There is a 220V charger to charge the batteries and a wall mounting kit to secure the device wherever you want. Devices can operate comfortably between 0 and +45 degrees. Devices can operate with 220 VAC-50  Hz city grid current; and built-in rechargeable lithium-ion batteries can be fully charged in a maximum of 4 hours. Fully charged batteries provide at least 80 shocks at maximum energy; or devices can run for at least 100 minutes. The total weight of the devices; including all accessories; does not exceed 12 Kg.

Defibrillator History

The first versions of defibrillators were shown in 1899 by two physiologists; Jean-Louis Prévost and Frédéric Batelli; from the University of Geneva in Switzerland. They discovered that small electric shocks can cause ventricular fibrillation in dogs; and larger loads will reverse the situation.

The external defibrillator; as it is known today; was invented in 1930 by Electrical Engineer William Kouwenhoven. William studied the relationship between electric shocks and their effects on the human heart when he was a student at Johns Hopkins University School of Engineering. His work helped him invent a device for the external operation of the heart. He invented the defibrillator and tested it on a dog like Prévost and Batelli. It was the first use on a human in 1947. American Heart Surgeon Claude Beck shocked the boy; who had a cardiac arrest during surgery with a deflator designed by his friend James Rand (Rand Development Corp); with two metal arms the size of two wings; and the boy’s heart worked again. The kid’s cured.
