Mod -80: Like I said before -“We can control DKA without insulin, but insulin is what Hashem put in our bodies and that’s what we want to use -the natural hormone.” Even though you’re being sarcastic, it’s true -you definitely can survive with a heart-lung machine without a heart. I personally haven’t witnessed long term survival on it, but that yungerman who had H1N1, I think was on it for awhile & B”H he is alive and well. Parental nutrition is given all the time and people live for extended time and they don’t drink or eat. As far as living without a head, we haven’t yet figured that one out in modern medicine, but I do think the Gemorah says that a person can live with their head cut off as long as there is no wind. Don’t ask me to explain this Gemorah.
Parental? Like in nursing a baby? Or did you, perhaps, mean parenteral? –77
