@DaveTweed I agree that the context of the question remains constant, and didn't change from the time it was posted till now. But it's TV show that is the point of departure for the question.
The question had confused some of our members, and they have labeled the question as an XY problem. The question lacked context.
To clarify this, I've asked the O.P. "what are you trying to accomplish?" The O.P. immediately brought up the TV series.
The O.P. isn't designing a defibrillator, neither he is a user of defibrillators. It's important that the users who will read the question in the future understand what the O.P.'s point of departure was. This is why the edit about the TV series should be included in the text of the question: it should have been there from the beginning.
