Please consider contacting hospice. We entered the hospice program in February for my mom who has end-stage COPD. I can tell you that the hospice staff are absolute angels. The primary mission of hospice is to help keep the patient as comfortable as possible during the final stages of life. They do not attempt to cure a patient, but do keep in close contact with the doctor to ensure that the proper meds are ordered and administered.
If a patient needs a hospital bed, wheelchair, walker, bed-side comode, hospice will provide those things. Hospice also provides a social worker, CNA, and chaplain.
Getting started can be rather overwhelming, but once a routine is in place, it's a God-send. They not only provide care for the patient, but the primary caregiver and family as well.
You are in my prayers, and take care.
