Grandmas survival

My grandma is currently in ICU and is fighting for her life. She woke up one morning feeling sick, not COVID related. They insisted on open heart surgery since she can’t breathe but as a family we feel she’s to weak for a major surgery like that. She has a sever UTI that won’t go away and she is having a hard time breathing alone. We are not able to visit and hold her hand through this situation. We’re motivation for her to keep living. She’s been in the hospital for almost a week. She may not make it and doesn’t have life insurance or a burial plan besides cremation. She has 4 children and lots of grandchildren who love her so much. She is the backbone to our family. Anything helps for medical expenses or surgeries she may need to get her home.
