NEW YORK, June 29: A 10-year-old Pennsylvania girl who sparked a national debate about child access to organ donation took her first independent breath this week on a second set of donor lungs after her first transplant failed, the girl’s family said yesterday. Sarah Murnaghan, who had cystic fibrosis and needed a lung transplant, had been kept off an adult organ transplant list due to an age restriction. She became eligible for an adult pair of lungs only after a judge’s order. (agencies)
