- OK, here's my 2 cents. I'm just a student in electrical engineering, and
- I've only taken one class in biomedical engineering.
-
- What I have learned is that current is the killer. These numbers that
- people are throwing around all depend on the situation. 100mA is not going
- to kill you if you're holding the leads. I do believe that 100mA through
- the heart will certainly kill you, but I remember that if you're holding the
- leads in your hands (dry), the 100mA range is somewhere near the "let-go"
- threshold, which means that you won't be able to let go of the wires. Above
- that are various levels are shock and such, but it takes a lot more to kill
- you.
-
- And, think about this. You can't just say 120V will kill you, since we've
- already established that current kills. Think about the defibrillators they
- use in hospitals. I believe many defibrillators give a 3000V shock, but can
- go up to 5000V. Clearly it's not the voltage since these levels should kill
- the person, and obviously a doctor isn't going to kill the person who's
- heart is going into fibrillation.
-
- OK, you can start flaming me now.
