Automated External Defibrillator (AED)
October 12, 2017 | medi tech | MedDevice
A Defibrillator (“Defi” for short) is a medical device that is able to stop life-threatening cardiac arrhythmias, such as ventricular fibrillation or ventricular flutter, by the targeted delivery of electric shocks. In addition to defibrillation there is the cardioversion, which works with lower energy levels and is used for example in the treatment of atrial fibrillation. An Automated External Defibrillator , AED for short , is a so-called lay defibrillator, It can also be used by people without medical education for life-saving defibrillation, such as cardiac arrest or cardiac arrest, heart attack or fibrillation. The special feature of an AED: It guides the user through the resuscitation process with the help of simple and easy-to-understand voice instructions and explains in detail how to attach the adhesive electrodes. Also the energy delivery regulate the AEDs automatically and without complicated attitude by the Ersthelfer. The cardiac rhythm is analyzed and the defibrillator’s electroshock is either performed automatically or the user is prompted to start the shock delivery manually on the device.
Sudden cardiac death and the benefits of nationwide AED care
Every year, thousand people suffer cardiac arrest outside a hospital. Only 10% of these patients survive, also because first aid measures are often not performed. In addition to cardiac massage, timely defibrillation to treat a cardiac arrest is of great importance. A recent study in the New England Journal of Medicine from DenmarkThe use of laminar defibrillators in patients with a cardiac arrest sustained outside a medical establishment correlates with a better outcome. Brain damage, long-term care and death decreased significantly. This disproves the frequently argued objection that the use of lay AEDs would increase the number of patients with irreversible brain damage. The provision of so-called “lay defis” in public spaces and better lay education in first aid measures can help save more patients with cardiovascular arrest suffered outside the hospital.
AEDs in public spaces
The automatic defibrillator (AED) is often found in public places and public buildings such as airports, train stations or public authorities. The long standby time achieved by long-life battery, the protection against falsely triggered defibrillation shocks and the sometimes automated check of the durability of the accessories, the Laidout provides a particularly high application security. The AEDs can also be used in pacemaker patients, as timely cardiovascular defibrillation takes precedence over any potential damage to the device.
