Needing money to pay for US medical bills

My mom and Dad were on vacation in Jamaica when part way through the trip my mom said she had issues and was taken to a hospital. Her medical condition was bad and had to go in for surgery with no success as damage to her body was severe, she needed better medical care. So the insurance company was medi-vac’d her to Miami as it was the closest hospital from their location at the time. She has been in the Miami hospital, alone, since November placed under a medical coma. The insurance company is running low on funds and we have exhausted all other options. And now I’m resorting to asking others for help to pay for a med-vac get my mom back up to Canada. Any little bit helps. Thank you for reading.
