I can sure understand his desire to die at home...damn tough situation. A friend of mine, retired USN CPO. After a bad injury, he spent his last months here.

If there is such a facility near you, I'd urge you to look into it. The rooms were spotless, care was 24-7, near hospital level.
I realize some places aren't so nice, but I really was impressed with this one. I was allowed to visit my friend whenever my schedule allowed. Good physical therapy if called for. The vets enjoyed each other's company.
