A bi-phasic defibrillator, DF 2617 uses current controlled biphasic defibrillation waveform for shock delivery. This is to ensure that the current is optimal, which in turn cause minimal damage to the heart tissues. The defibrillator features 100 charge/discharge of 300J with fully charged new battery. It enables the recording of up to 24 events. The LCD for sharp bright non-fade display enables a thorough viewing of the events. DF 2617 also comes with a noiseless thermal printing technology, which will eliminate the disturbance caused to the patient by normal thermal printers.
