The phrase “abbreviated life-span” is an interesting way to put it. It is reminiscent of a politically correct way of saying the patient actually died, “negative patient-care outcome.”

Macy; emc-p...@ieee.org Subject: Re: What is killer joules? Defibrillators dump energy as shocks rated at a max of 360 joules into the human. This stops the fibrillation of the heart by stopping the heart effectively 'killing' you, but the hope is that you don't stay that way. The heart will re-generate its electrical activity if there has not been a lot of damage from the fibrillation. The alternative to no defib is an abbreviated life span. BTW, if the paddles are not properly 'bonded' to the skin, the scorch marks are impressive. The information you are looking may be found by searching on defibrillation energy, joules, watt-seconds, FDA, etc. "Robert A. Macy" <m...@california.com> wrote: What is the amount of energy that kills a person? This may seem like mixing terms here, but: [If these limits are in error, please correct...] For example, maximum leakage in Medical Electronics for direct connection to patients is around 10uA Maximum leakage for AC mains RFI/EMI filters is 2 mA, and typically around 1 mA. These limits are based upon potential harm for some time period, and are specified using easily measurable current. But I need a limit based upon joules. For example, in the winter as we slide across the car seat, we don't die from the 18 Kv zap. low capacitance prevents lethal harm. So what 1/2 C V^2 kills people? Is there a published limit? Is there a reference for max allowed? Robert - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
