Final answer:
The final step in the AHA chain of survival is post-cardiac arrest care.
Step-by-step explanation:
Post-cardiac arrest treatment is the last phase in the AHA chain of survival, which also includes early EMS activation, early CPR, early AED use, and advanced life support. This pattern is known as the "Chain of Survival," according to the American Heart Association. The four interconnected links in this chain are early access, early ACLS, early defibrillation, and early basic CPR. The medical procedures and therapies given to a patient following a cardiac arrest and resuscitation are referred to as post-arrest care. This could involve taking steps to promote the patient's recuperation, address any underlying diseases, and stabilize the patient's vitals.
