Joseph raises another point.
I dont know the specifics of the question he is reffering to. But am certain as learned as any poster here thinks Joseph may be nobody was actually asking a halachic question regardign putting somebody on a respirator.
We all have an inate “halachic sense” most of us know what questions can be answered by aybody what requires a more learned person and what requires a Gadol. The idea that every question (eg Bracha on apples) needs to be addressed to a Gadol or even Rav is foolsihness.
It is clear in most threads when more invvolved questions are asked rarely (if ever) is the pesron actually asking and looking for guidance, rather it is usually to stimulate conversation (or argument).
