Angelrose, bless your hearts . I can only imagine what a very frightening time this is for you. It is truly wonderful your DH can follow commands and hold your hand, as that is a sign that he is aware you are there.
I am sending lots of prayers you will be granted strength and hope during this difficult time and that your DH's team of drs can heal him and he has complete recovery. DH and I are about your ages and married 45 yrs., so I realize all too well this could just as easily be us and truly sympathize with your heartache. Please do lean on your faith, family, friends and medical team, and know that Dis'ners are a very powerful bunch when we pray together. Godspeed
