The issue of chassis leakage currents flowing through areas on the surfaces of patients' bodies is again being discussed.
Reported relevant experiments have not attempted to duplicate the conditions existing for the situations of concern - an open ground, a person touching the chassis of the device that has an open ground condition, and this person then touching the patient; or a grounded patient touching an ungrounded chassis.
The results did not confirm previous findings in another study that currents ranging from 261 to 500 microamperes caused pain.
They were closer to those of a study of perception of 60-Hz current, in which similar currents elicited only perception.
