AED Defibrillator – NSL FRED-PA-1 Schiller (Swiss)




By lifting up the device cover, the FRED PA-1 starts up immediately and guides the rescuer step-by-step during the entire resuscitation process.

The FRED PA-1 is available either as semi-automatic or fully automatic device.In its automatic version, the FRED PA-1 delivers the shock without any action of the rescuer. In its semi-automatic version, the FRED PA-1 prompts the rescuer to deliver the shock by pressing the shock button.


  • Ease of use: interface with 1-2-3 steps
  • Pre-connected electrodes for faster application to the patient’s chest
  • Automatic self-tests for detection of electrode expiration and battery capacity
  • Trilingual: perfect for an international environment


AED Defibrillator is a treatment for life-threatening cardiac dysrhythmias, specifically ventricular fibrillation (VF) and non-perfusing ventricular tachycardia (VT).[1][2] A defibrillator delivers a dose of electric current (often called a countershock) to the heart. This depolarizes a large amount of the heart muscle, ending the dysrhythmia. Subsequently, the body’s natural pacemaker in the sinoatrial node of the heart is able to re-establish normal sinus rhythm.[3]

In contrast to defibrillation, synchronized electrical cardioversion is an electrical shock delivered in synchrony to the cardiac cycle. Although the person may still be critically ill, cardioversion normally aims to end poorly perfusing cardiac dysrhythmias, such as supraventricular tachycardia.[1][2]

Defibrillators can be external, transvenous, or implanted (implantable cardioverter-defibrillator), depending on the type of device used or needed.[4] Some external units, known as automated external defibrillators (AEDs), automate the diagnosis of treatable rhythms, meaning that lay responders or bystanders are able to use them successfully with little or no training.

Defibrillation is often an important step in cardiopulmonary resuscitation (CPR).[5][6] CPR is an algorithm-based intervention aimed to restore cardiac and pulmonary function.[5] Defibrillation is indicated only in certain types of cardiac dysrhythmias, specifically ventricular fibrillation (VF) and pulseless ventricular tachycardia.[1][2] If the heart has completely stopped, as in asystole or pulseless electrical activity (PEA), defibrillation is not indicated. Defibrillation is also not indicated if the patient is conscious or has a pulse. Improperly given electrical shocks can cause dangerous dysrhythmias, such as ventricular fibrillation.[1]

Survival rates for out-of-hospital cardiac arrests are poor, often less than 10%.[7] Outcome for in-hospital cardiac arrests are higher at 20%.[7] Within the group of people presenting with cardiac arrest, the specific cardiac rhythm can significantly impact survival rates. Compared to people presenting with a non-shockable rhythm (such as asystole or PEA), people with a shockable rhythm (such as VF or pulseless ventricular tachycardia) have improved survival rates, ranging between 21-50%.
