Defibrillator – NSL Defigard 5000 Schiller (Swiss)

HOSPITAL DEFIBRILLATION

DEFIGARD 5000

DESCRIPTION

The DEFIGARD 5000 combines the efficacy of a biphasic pulsed defibrillator (Multipulse Biowave) with precision monitoring on a large colour screen.

The big size of the colour screen (10.4“) allows the  simultaneous display of up to 12 ECG leads. The navigation button and direct soft keys give you quick access to all parameters and menus and make the device extremely user-friendly and easy to use.

FEATURES

  • Defibrillation is possible using adhesive pads, external paddles or internal spoons
  • Data saving: internal memory allowing storage of 45 minutes of ECG and 500 events in AED mode, as well as 24 hour trends, both graphic and tabular, for all parameters
  • Download of AED data via the USB port using a memory stick
  • Software upgrades via USB memory stick or Ethernet connection

 

Description

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%.
