a few ideas for you. have his Neurologist or Palliative care doctors determine if he can make his own health care decisions. if not ask for a letter stating that he cannot make the decisions. make sure all his other doctors have a copy of the letter. take a copy of the letter to your lawyer and ask for a Power of Attorney for both healthcare and financial decisions. then have a DNR completed and signed by his doctor. keep a copy in your wallet and post the original on your refrigerator. there are also a few other documents your lawyer can help you with too. good luck and remember HE is SCARED shitless and the Calvary is Not Coming. take care of your self!
