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

5 back blows, 5 abdominal thrusts, and perhaps alternated between the two

Explanation:

Firstly, when should we do the five-and-five approach?

It is highly recommended to the five-and-five approach when the person choking cannot forcefully make themselves laugh, talk, etc.

Steps of the Approach:

Step 1: Give 5 back blows

           - if the person choking is an adult, stand to the side and right behind

           - if the person choking is a child, kneel down behind them

           - put an arm across the adult or child's chest

           - bend the person over at the waist

           - give five separate back blows (hit them strongly ) between the person's shoulder blades with your hand's heel

In this case, Calla's sister is 10 year old, meaning she kneels down behind her. Calla put her arm across her sister's chest for support, and then she bended her over at her waist. After that, Calla firmly hit her sister in the back between her shoulder blades with the heel of her hands.

Step 2: Give 5 abdominal thrusts

            (for children)

           - put your arms under the child's arms and around the upper bit of their abdomen

           - clench one of your fists and place it between their ribs and the navel

           - grip this clenched fist with your other hand and pull sharply inwards and upwards five times

           (for adults)

           - put your arms around their waist then bend them forward

           - clench one of your fists and place it above the adult's belly button

           - grip this clenched fist with your other hand and pull sharply inwards and upwards five times

Again, in this case, Calla's sister is a child. Calla put her arms under her sister's arms and around the upper bit of her abdomen. She clenched one fist and placed it between her sister's ribs and navel. She grasped the fist with her other hand sharply pulled inward and upward five times.

 Step 3: Alternate between the five back blows and abdominal thrusts

             - Do the procedures listed above alternatingly until the blockage

            is cleared and the adult or child stops choking

Calla gave her sister 5 back blows and 5 abdominal thrusts alternatingly until she finally got her sister to stop choking. Additionally, the blockage was removed.
