Biphasic defibrillator

Bobath concept

A device used to the heart defibrillation that is reestablishing the normal cardiac rhythm by delivering a therapeutic dose of electrical energy to the heart. The direct current shock given by a biphasic defibrillator has a biphasic wave form. The initial direction of shock is reversed by changing the polarity of the electrodes in the latter part of the shock being delivered. Usually the initial voltage applied is higher than the reversed polarity shock (initially the energy of 150 – 200J is delivered, and then 150 – 360J).
