The primary purpose of Activated Charcoal in emergency medicine is to prevent absorption of toxins from the gastrointestinal tract into the bloodstream. Activated charcoal works by adsorbing (not absorbing) the toxic substances within the stomach and intestines, which allows these toxins to be eliminated from the body through the gastrointestinal system rather than entering systemic circulation. This is critical in cases of poisoning or overdose, where minimizing the amount of toxin that reaches the bloodstream can significantly reduce the harmful effects on the body.

The mechanism involves the large surface area of activated charcoal, which binds with various drugs and chemicals. By doing so, it effectively "traps" these substances, preventing them from being absorbed by the body and allowing them to be excreted later. This is a key intervention in many emergency situations involving ingested poisons, making it an essential tool in pre-hospital care and emergency departments.

Understanding this function is vital for EMTs and other healthcare providers, as it guides their approach to treating patients who present with certain types of poisonings. It's also important to recognize the limitations of activated charcoal; it is not effective against all substances, and it should not be administered in cases where the airway is compromised.
