My prayers are with you and your family,
Watch the spouse too. If they are a true team, she'll need just as much help as he does Make sure she has a outside life away from the hospital, I know thats difficult, especially to pry her away from his bedside, but she'll need exercise of all types, mental, physical and social. Dont let her get so involved that she has no life.
After watching my mom nearly come completely apart when dad passed after 7 years in the nursing home from a paralytic stroke after a bypass, it must be done. Mom insisted on being at that nursing home 14 out of 24, 7-365 volunteering at feeding 3 meals a day, and not just with dad. Plus she handled ALL the medicade paperwork and drove 30 miles a few times a month to battle it out with the social workers and insurance. Mom considered herself "ON CALL" at all times. resulting in zero personality and much anger whenever a aide or nurse made even the simplist mistake. More then once I was down there and heard on the PA, " Mrs Roberts has left the building".
I admire her strength, and helped her when I could, but what happened next was very ,very, dark.
Mom suddenly had no where to go one day after hospice, and crashed, physically and mentally. It took me a year to get her to even travel across town or discuss the weather.. All she'd talk about was the struggle with dad, which turned off family and friends fast. Wouldnt go to church, the mall or a movie,or see friends,or her physician. I hate to be the ghost of Xmas past, but DON'T loose #2 (or 3 or 4) in the process of helping #1. Prevent possible severe depression and possible martyrdom. That goes for you too. Get somebody ouside your close support system to periodically get you out of there,check what your doing and dont close the home lab down. Keep posting here.
She's coming around now, at almost 2 years, but it was scarry.
best wishes for a hopeful outcome.
