Sorry that you are both going through this, Merm. If you are in the US, and your mom is on medicare, one option is the hospice benefit which will provide some caregiver visits and equipment such as hospital beds at home. This option is available if a doctor will certify that the individual has less than 6 monthes to live, and the paperwork is filled out. This may be a long ways down the road for your mom - but I would urge you to try for the benefit as soon as possible: most people wait to long to get the full benefit of it. My dad spent 2 months under hospice when he had congestive heart failure, and the hospice personnel made them good months insofar as possible.
