It's been over 15 years since I actually worked in the biomedical
engineering field so my memory is a little dim, but if you do a google on
biomed standards one item I pulled up is here
http://www.ohmicinstruments.com/pdf/BET300.pdf .
This is a test instrument we used to check any electrical equipment that
could be hooked to a patient such as a  heart rate monitor. The "Upper
range" of leakage current is 20 ma but
I believe the "limit" was usually in the range of a couple hundred
micro-amperes. This is a link to a book that discusses it.

has drifted off topic but I post it for the curious.
