After two cardiac arrests occurred on its premises over the last 6 months, a large home improvement center has purchased a fully automated AED. You have been asked to provide education on its use. During an instructional session, a student asks you what will happen when the AED indicates that a shock is indicated. Your response should be:

According to Unitek EMT, if a device advises you to, you should deliver one shock, then immediately resume CPR, starting with chest compressions, or give chest compressions only, for about two minutes. You can then use the defibrillator to check the person's heart rhythm. If necessary, the defibrillator will give another shock. You should repeat this cycle.  Shock is a clinical syndrome with four stages: initial, compensatory, progressive, and refractory. There are broadly four types of shock: distributive, cardiogenic, hypovolemic, and obstructive.  Here are some types of... Show more

Shock is a clinical syndrome with four stages: initial, compensatory, progressive, and refractory. There are broadly four types of shock: distributive, cardiogenic, hypovolemic, and obstructive. 
Here are some types of shock:
Cardiogenic shock: Occurs when the heart has been damaged to the point where it cannot pump enough blood to meet the body's demand for oxygen. A heart attack is the most common cause of cardiogenic shock.
Hypovolemic shock: Occurs when there is a decrease in circulating volume. This can be caused by hemorrhage, vomiting, diarrhea, excessive perspiration, or fever. Signs and symptoms of hypovolemic shock include elevated heart rate, hypotension, tachypnea, acral cyanosis of the extremities, and cold, clammy skin.
Anaphylactic shock: Occurs when there is a loss of vasomotor tone following the massive outpouring of vasoactive mediators resulting from the degranulation of mast cells and basophils.
Septic shock: Occurs when there is impaired tissue perfusion in the context of an inflammatory response. This may be traumatic or surgical, or it may involve local inflammation, infection, severe burns or the presence.
