Charcoal hemoperfusion is primarily used to treat severe poisoning, specifically in cases of overdose or poisoning by certain types of drugs and toxins. The process involves passing blood through a column that contains activated charcoal, which adsorbs a wide range of substances, including medications and harmful agents, effectively removing them from circulation.

In instances of severe poisoning, rapid intervention is crucial, as it can prevent further absorption of the poison into the bloodstream and mitigate the potential for organ damage or failure. Standard treatments may not be effective for all toxic exposures, making charcoal hemoperfusion a valuable tool in emergency medicine for situations where patients present with life-threatening levels of toxic substances.

Other options, such as treating mental health disorders, cardiovascular issues, or respiratory distress, do not directly align with the specific application of charcoal hemoperfusion, which is primarily focused on the removal of toxic substances from the bloodstream rather than providing direct treatment for those conditions.
