The BeneHeart D1 is a powerful automated external defibrillator (AED) that provides support throughout the emergency response process and is based on biphasic technology which allows the delivered energy to be escalated to 300J and 360J. The light-weight, compact, durable and easy-to-use defibrillator offers all standard AED functions and allows the user to improve the defibrillation success ratio by increasing the dose of subsequent shocks.
