Defibrillation trainers should idly provide platforms to train on different heart rhythms and defibrillation techniques. But most trainers available in markets are limited to CPR techniques and rhythm generators. Our R & D has come up with a solution for the same in the form of Advanced Defibrillator Simulator. ADS provide a complete simulation package and simulates all aspects of an original defibrillator. And students and trainers can work on the same without the fear of shock. Also ADS can be used on any simple manikin and eliminates the use of rhythm generators.
