LINCOLN, Neb. (AP) – Authorities say a Lincoln police officer saved the life of choking baby. Police say the 1-year-old girl was choking on a balloon and not breathing when Officer Ryan Duncan arrived at the scene around 6:30 p.m. Saturday.  According to Omaha television station KETV, police say Duncan performed “back blows” on the baby until part of the balloon dislodged. The Mayo Clinic describes “back blows” as a first aid technique in which a choking child is thumped on the back while positioned with his or her head down. The baby was taken to a hospital and was expected to recover.
