PHILADELPHIA — A 10-year-old Pennsylvania girl recovering from two double lung transplants is expected to be released from the hospital this week, a spokeswoman for the girl’s family said Monday.

Tracy Simon said a final decision hasn’t been made on exactly when Sarah Murnaghan will leave Children’s Hospital of Philadelphia.

The Newtown Square girl with end-stage cystic fibrosis received the transplants earlier this summer after a federal judge intervened in her parents’ lawsuit challenging national transplant rules. Sarah’s case spurred a national debate over the process of getting organs.

Janet Murnaghan said Sunday that her daughter was taken off oxygen, although she still gets support from a machine that helps her to breathe, and has started to walk with the aid of a walker.

Simon said Sarah’s recovery is now focused on building her muscle strength so she no longer has to use a breathing tube. She said Sarah recovered from a case of pneumonia that stemmed from the tube.
