According to my source, during a code, the De-fib machine is in Joules, and the first shock is started at 200, then progressively moved up to 360, if the Pt is still in fibrillation they start again only this time it is started the second time at 360.
For this procedure Body resistance is of no concern, but stopping the fibrillation is whether it be Atrium or ventricular. They grease the paddles with a conductive lubricant and one goes on the left side and to the center of the chest, it is not like a Hand to foot electricution. Didnt someone say that for Legal electrocutions the body resistance is down to about 130 ohms at 25000 volts, .......Talk about overkill huh ? That ought to do it and then some.
