What technique is used to help expel an object from the airway of a choking person?

The technique that is used to help expel an object from the airway of a choking person is back blows. This technique involves delivering a series of forceful blows to the person's back while they are in a slightly bent forward position. It is particularly effective when the individual is conscious and able to cough or make sounds, as it can help generate enough force to dislodge the object from the airway.

Back blows are often used in conjunction with other methods, such as abdominal thrusts, especially when back blows alone may not be successful. It's important to note that the method chosen can depend on the situation, including the level of consciousness of the choking individual.

In cases where back blows are not sufficient, abdominal thrusts may be performed to provide a strong upward force against the diaphragm, which can help to push the object out more forcefully. However, back blows are a critical first step and can be particularly useful for those experiencing mild choking.

Finger sweeps are not recommended unless you can see the object and it is safe to remove it, as attempting to sweep without visibility could push the object further down the airway.
