The five and five method is a series of alternating moves used to dislodge things from someones air ways.

five back blows (method below)

Stand behind the person to the side. Place one hand on their chest and have them lean forward at the waist. With the heel of your hand, give five sharp back blows in the area between the shoulder blades. After each blow, check to see if the obstruction has cleared.

and five abdominal thrusts (method below)

Stand behind the person. Wrap your arms around the waist. Bend them forward slightly. Make a fist and position your fist above the person’s navel (bellybutton). Cover your fist with your other hand. Quickly thrust both hands inward and upward, as if trying to lift the person up. Do five thrusts.
