When should you use back blows for a choking adult?

Using back blows for a choking adult is appropriate when the individual is unable to cough, speak, or breathe. This situation indicates that the airway is likely obstructed, and the obstruction is severe enough to prevent air from moving in and out. In such cases, back blows can help dislodge the object causing the blockage.

Applying a controlled series of back blows can create enough pressure to help expel the object from the airway, restoring the person's ability to breathe. Performing these actions in a timely manner is critical, as prolonged choking can lead to a loss of consciousness and severe complications.

In contrast, if someone can cough or speak, their airway is not fully obstructed, and encouraging them to continue coughing is the best course of action, as it might help clear the obstruction naturally. Waving their arms is often a sign of distress but does not indicate the need for back blows without the presence of severe choking symptoms. Observing someone swallowing does not warrant back blows either, as it suggests that they are still able to manage their airway. Thus, back blows should be reserved for situations where the individual is in significant danger due to a complete blockage of the airway.
