On September 18th, 2023, the American Heart Association published clinical management guidelines for cardiac arrest and critical cardiac conditions caused by poisoning in the journal Circulation. Based on the differences in drug toxicity effects, our team has systematically interpreted the guidelines in three parts. This article, as the third part, focuses on interpreting the clinical management strategies for cardiac arrest caused by cyanide, organophosphates, carbamate and methemoglobinemia, and reviews the application of veno-arterial extracorporeal membrane oxygenation in poisoning treatment. Through in-depth analysis of the key recommendations in the guidelines, it aims to provide reference for clinical diagnosis and treatment.
