When Dylan Nelson was admitted to the ICU in July with difficulty breathing, his mother, Kim Barnes. figured it was his asthma acting up. But when she got to the hospital in Burlington, Wis., he couldn't speak. He was intubated. His blood oxygen level was only 10%. He was put into a medically induced coma.
Barnes told the nurse she worried she wouldn't see her 26-year-old son again. The nurse reassured her.
