Hello -
It is technically possible to code while on life support, although it's kind of a grey area. If the heart stops producing its own sinus impulse, eventually, over a period of anywhere from a few seconds to a few hours, the heart will stop beating on its own. "Life support" generally means maintaining artificial mechanical respiration, which tends to give the heart an atrial "kick" and keep it beating, but if the sinus node fails, and the ventricles then slowly fail also, once cardiac activity stops and is unexpected and unplanned (depending upon whether the patient had a "do not resucistate" -- DNR -- or not) the code is called. Otherwise it's considered that the patient simply "expired." The result is the same if there is a DNR order or if the heart's electrical system simply won't respond anymore.
If there is no DNR and the patient's heart is restarted, it is a code with successful resucitation.
As I said, it's something of a grey area, as some people mean by "coded" that the heart stopped, which is entirely possible while on life support.
I hope this answers your question and reassures your friend.
