What should you avoid using in the case of an FBAO?

In cases of a foreign body airway obstruction (FBAO), avoiding a blind finger sweep is crucial because this technique can potentially push the obstruction deeper into the airway rather than remove it. The primary goal during an FBAO is to clear the airway in a safe and effective manner. Performing a blind finger sweep can result in further injury or complications, as it may also cause the obstruction to impact more firmly against the throat walls.

In contrast, back blows, abdominal thrusts, and chest compressions are techniques recommended for managing an FBAO. Back blows can help dislodge the object by creating a forceful airflow that may push the foreign body out. Abdominal thrusts (Heimlich maneuver) are particularly effective in generating intra-abdominal pressure that can expel air forcefully upwards, which may help clear the airway. Lastly, chest compressions may be used in unconscious patients to create pressure and push out obstructions.

In summary, the avoidance of a blind finger sweep in FBAO scenarios is rooted in the need to maintain airway safety and to effectively manage the obstruction without risking additional harm.
