HELLO. What is the difference between monophasic and biphasic defibrillators?? And how many joules do you charge each one. How do you determine the amount of joules to administer? thank you.

monophasic is basically DC current. It passes in one direction from one paddle to the next. Biphasic is like an AC jolt, part of the shock goes from one paddle to the next and then reverses from the opposite paddle back. Less energy is required for the same effect.
I believe the joules for monophasic 360, and a biphasic is 200. Therefore there is less myocardial damage using a biphasic defibrilator and many studies that show better results in converting VT and VF. During a code, I believe current ACLS guidlines state that if you are using a monophasic you just keep it on 360 joules for every shock, and if you don't have instructions to the contrary, keep the biphasic defibrilator set on 200 joules.
