If you could get him into Hospice care that would be great for you.
My Mom was in palliative care for 2 weeks at the end. I had to explain to my Dad that the doctor had said that just having a DNR was doing nothing but prolonging the situation, her heart was failing and her system was shutting down. The Doc. strongly recommended Hospice because if they kept her in the hospital section, she would have to have an IV and feeding tube which was just prolonging the situation.

Once I got him to understand and agree to that I found that the nurses that are there are so gentle, kind, caring, etc. They explained to me what to expect as the process went on. My Dad, though, had a tough time being in the hospital room as there was no IV, no IV feedings.

Mom was tough, she was there longer than they thought she would be and I was there at least 12 hours of every day.

The sad thing is that after Mom passed, Dad blamed me for convincing him to put her into hospice. Counseling told me that was part of his grieving process but it took about a year or so before he realized it had been for the best. Mom had suffered a stroke 8 years earlier and had been paralyzed on her right side and couldn't talk. She had been in a nursing home all that time. I thing I noticed is that if one doesn't talk to people they tend not to talk to you so in someways she was, I hate to say, ignored. Not in care, but in - oh you know what I mean.
