The 10-year-old girl whose predicament sparked a national debate on organ donations is recovering after receiving two new lungs, her mother said Wednesday.  Janet Murnaghan, the mother of Sarah, wrote on her Facebook page that her daughter is "improving" after receiving two adult lungs in a double-transplant.  RELATED: PHILADELPHIA GIRL GETS LUNG TRANSPLANT  The Philadelphia-area mother said that Sarah was moved Wednesday from being on a heavy-duty respirator to a more traditional ventilator, calling it a "big step" in her recovery from last week's taxing surgery.  Sarah suffers from cystic fibrosis, a condition that made her lungs fill with fluid. In a last-ditch effort, her mother posted a petition on Change.org last month after it was clear that Sarah was not going to receive a pair of children's lungs in time to save her life.

The family wrote on their Change.org petition page that they were thankful for the overwhelming support of the some 373,000 supporters who signed the petition, and pointed out that Sarah's case has helped start a dialogue within the Organ Procurement and Transplantation Network (OPTN) board.  "As difficult as this process has been post-surgery, we appreciate the OPTN has now opened the door for other children in Sarah's unique position to become eligible for adult lung transplant," the family wrote on the website, thanking those who have given Sarah a greater shot of survival.
