A defibrillator is used for saving lives in emergency medicine during cardiac dysrhythmias and during ventricular defibrillation. The device delivers countershock using electric current and recuperates an individual's electric state of the heart to beat in a pattern that can be controlled. The electric shock depolarises the heart muscle and hence brings back the normal conduction. Early in 1899, it was found that smaller electrical charges created ventricular fibrillation whereas large electrical charges reversed it and hence defbrillation as a concept was born. From paddle type bulky electrodes used in 1950s we have advanced to the modern day portable lesser weigh defibrillators. Defibrilaltors are no more limited to hospitals and emergency care set-ups. Automated external defibrillators, also called as PAD (Public Access Defibrillators)are installed in public places to save lives.
DF 2509/R is a portable defibrillator/monitor powered by internal battery or AC powered. They combine a 360 joule defibrillator, ECG monitor in a compact, lightweight package. The salient features include display of ECG, ECG lead selection heart rate. Heart rate alarm, QRS volume control, every selection fast charge, auto disarm, massages and alerts.
Operating Controls And Indications
The defibrillator controls and indicators are located on the front panel. AC inputs receptacle and the equipotential earthing pin are located on the rear side of the defibrillator.
The Front Panel Operating Controls
The defibrillator function controls and indicators are located on the right side of the keypad. The printer functions controls; are located at the center of the keypad. The ECG monitoring functions controls are located towards the left side of the keypad.
DF 2617 AED is a current controlled biphasic defibrillator with guided CPR . Enables storage, recall and printing of events, and AED with voice and visual text prompts; records ECG before and after shocks.
