Calla sees her 10 year old sister choking. She does the five-and-five approach. What did Calla do?

The five-and-five approach for a choking person alternates five firm blows between the shoulder blades with five abdominal thrusts. Calla therefore gave five blows on her sister’s back first, then five abdominal thrusts. This is different from CPR, which uses chest compressions and rescue breaths.
