Ge disease etc. the machine is available in surgical/electrical stores.pediatric defibrillator is a special machine, that will deliver low joules of electricity(7to14)

When an aged adult are any human being whose heart has stopped due to hart attach cannot be revived,unless  defibrillator is putting to use.From time immemorial,medical curriculum teachers to practice C P R(cardiopulmonary rescisitation) the author must have have tried several hundreds of car whith out single success.should we still practice this!
