What treatment should be prioritized for a patient with known toxins during cardiac arrest?

In the case of a patient experiencing cardiac arrest due to known toxins or an overdose, the most critical action is to treat the overdose appropriately. This is essential because the underlying cause of the cardiac arrest is the toxic substance affecting the patient's physiology. Administering specific antidotes or supportive care targeted at countering the effects of the toxin can significantly improve the chances of restoring normal cardiac function.

While immediate CPR and defibrillation are generally crucial in the management of cardiac arrest, these interventions alone may not address the root cause of the patient's condition if the arrest is primarily due to toxicology. In cases where toxins are involved, addressing the overdose takes priority to reverse the effects of the poison and potentially stabilize the patient.

Monitoring vital signs is important in any emergency situation, but in the context of a toxic overdose leading to cardiac arrest, it serves as a supportive measure rather than a direct course of action for reversing the life-threatening effects.
