AED/Defibrilator Voltage

Postby prmdc_girl91 » Mon Jan 11, 2010 7:49 pm

Sorry...ANOTHER question.
What do AED's shock at?
And defibrilators...biphasic are...120 and 200 J?
Thanks

Monophasic is extinct(almost),AED typically fire at 150,200 or 360.There is constant debate about high current vs low current but they have similar morbidity rates.

Most defibs that i have used at the low end are 200.Again even in manual defibrilation ther are also two schools of thought on starting point.

Don't want to nitpick here, but something isn't jiving with me here.

The initial question was about the voltage, then the op references joules.

Joules are a measure of power, not voltage. Power is calculated by multiplying the voltage and the current together. To get your 200 joules (or whatever the defib is shocking at) you would multiply the voltage and the current of the shock together. Methinks the voltage woudl likely be high, and the current quite low... DH?

I may have presumed she meant joules.I only recall voltage being discussed when it came to power source and battery charging.

If she did indeed want the voltage delivered in a shock....NFI.Thats why im a fireman now :confused: :p

Most AED's deliver all shocks at 200 except for manuals.

Fair enough. Bothj were referenced in the original post. I do some electrical work with the full time gig, and voltage and joules weren't jiving together

I was under the understanding that Life Pack 500s that we use at our station shock at 200-300-360J's and the Life pack 12s that I use at work are the same 200,300,360,when not in manual mode.

Yes sorry I phrased that wrong. Thanks to everyone who was able to read past my mistake!
