Adult Chain Of Survival 1. Early access (if alone with a nonresponsive adult, call 9-1-1 before caring) 2. Early CPR 3. Early defbrillation 4. Early advanced care.
Pediatric Chain Of Survival is 1. Prevention of arrest (most likely respiratory or bleeding) 2. Early CPR (for 2 minutes if you are alone) 3. Early access (Call 9-1-1) 4. Early advanced care.

Understanding The Symptoms Of Heart Attack, Stroke And Cardiac Arrest
Heart Attack symptoms can range from slight to severe. Typical symptoms are chest pain lasting 15 to 20 minutes (sometimes intense, not always). Other signs may include sweating, nausea, vomiting or shortness of breath. Atypical signs include vague, nonspecific complaints. Some people may present with only weakness. Symptoms such as shortness of breath, syncope (fainting), or lightheadedness. If symptoms are recognized you should have the person sit and rest comfortably. Help them take prescribed medication. Call 9-1-1. and give oxygen if available.
Stroke symptoms include weakness or paralysis on one side of the body or face, and/or inability to speak or understand. Sudden numbness or weakness on one side of the body. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eves. Sudden trouble walking, dizziness. Sudden severe headache with no known cause. Ask the person to 1. smile 2. raise both arms, 3. answer a simple question. Problems with one or all you should Call 9-1-1.
Cardiac Arrest victims are nonresponsive, lifeless, not breathing or not breathing normally (gasping breaths). Make sure 9-1-1 is activated and begin CPR and defibrillation as soon as possible.

Responsive Choking is when a person is still conscious and is unable to speak or make noise. A person who is coughing or gaging is not choking. If it is an adult or child encourage them to cough. If it is an infant be prepared to help if the symptoms worsen. For the responsive adult or child who is choking provide abdominal thrusts until the object is expelled (can make noise) or the person becomes nonresponsive. If the person is obese or pregnant use chest compressions while standing in place of abdominal thrusts. For a conscious choking infant use 5 back slaps followed by 5 chest thrusts until you hear noise or the infant is nonresponsive.
Nonresponsive Choking (Adult, Child and Infant) CPR with looking in the airway to check for the object before giving breaths.
