A Utah infant who underwent a heart transplant Nov. 12 has been upgraded from critical to fair condition at the Loma Linda University Medical Center.

Whitney Ray Petersen had been in critical condition and on a respirator since his operation, a hospital spokesman said. He is now breathing on his own.Cynthia Petersen said her son's slow recovery had worried her until Tuesday.

"We were worried because one (transplant) baby was off the critical list in 18 hours, and another one was off in three days. The problem was that he had a lot of stuff in his lungs, and they weren't getting any better. But doctors could tell from his X-rays Monday that he had improved," she said.

Meanwhile, about 20 Utah friends of the Petersen family have organized a fund-raising activity to help with the $150,000 to $200,000 cost of Whitney's care. The group will be making and delivering pizzas, which they will sell for $6.50 to $8 each.
