What to do when I am unable to be a sole caregiver

I live 14 hours away from my elderly mom..Who is currently in SNF until the allotted days run out..Already spoke to SW's and case managers..Applied for Medicaid but have already been told that it will likely be denied.. So the issue that I am trying to research is this.. What if family is unable to physically and financially care for my elderly bedridden mom ( she is unable to walk, stand, is incontinent of bowel and bladder) needs long term 24-7 care...Mom is medically fragile, requiring continuous oxygen, nebulizer treatments every 4 hours, numerous meds including around the clock including narcotic pain meds.. What happens? Mom certainly falls between the cracks..She is due to leave skilled very soon.. She will not be eligible for Medicaid until this fall..The 5 year asset rule.. But there aren't enough assets to pay for around the clock home nursing care for any length of time, even if one could find this type of nursing care available in her neck of the woods.. What can one do when there isn't anywhere to turn?
