You're posts are incorrect and not clear at all.
Here's her discharge summary. I don't give a fig what you've read into what the ME said; the doctors who actually attended her in the hospital have been clear.

Included in there you will find:
She had cardiac arrest, severely low potassium (3.7 is low enough to make you 2x more likely to have cardiac arrest (which is not a heart attack) hers was a 2.0,
She was in a coma, on a ventilator, and her tube was put in there at the hospital, NOT "at Michael's request for the convenience of the nurses"
She was malnourished and low in calcium
LOL, you're whacky. "Convenience of the nurses"? You just make it up as you go. You have no credibility with me. Try somebody else who is easily browbeaten by and susceptible to straw dogs.
