Descriptive ethics will hence try to oversee whether ethics still holds its place. Because descriptive ethics involves empirical investigation, it is a field that is usually investigated by those working in the fields of evolutionary biology, psychology, sociology or anthropology. Information that comes from descriptive ethics is, however, also used in philosophical arguments.
To deactivate an ICD or alter pacemaker function, a magnet has to have a field strength of 10 gauss (a unit of magnetic strength) or greater next to the surface of the device. A magnet in a stereo speaker has a field strength of 100 gauss at the surface - but 0 gauss 6 inches away.
If a pt has this AICD/pacer then we use the magnet to TURN OFF THE DEFIB aspect of the device so it won't shock pt - ie pt with runs of VTach but is being made comfort care (withdrawl/no shock). The magnet will flip a switch so the device can not read/respond to shockable rhythms.
