Mercy flight medical cost for Elizabeth Balon

This is for the transportation of our mother from Nevada to New York for medical bills and Mercy flight.
  While in Nevada my mother standing next to my father was hit from behind by a young adult.  She lounged at my father after saying it felt like she punched her. The lady disappeared. Presently the police are in an investigation. Shortly after my mom was complaining about her back hurting her. She could not sleep that night and was having bad pains the next day. She passed out on my father who called 911 when she was rushed in they found she had a ruptured thoracic aorta. She was rushed into surgery for repair but they had to counter her blood thinners quickly and it caused blood clots. She now has clots in her right leg which they say they can't remove her leg which she needs for survival. She has a clot in her Spin causing paralysis in her from the waist down. Plus several strokes one major. She was left with no kidney function because of all the contrast they used for the mri's  
   She is communicating with us and getting stronger but she needs a better hospital in order to remove her leg and have a shot at survival.  
    Thank you for your time and any help is greatly appreciated.
