Shock occurs when the circulatory system, for various reasons, does not provide enough blood flow to the body’s organs and tissues, rendering them deprived of oxygen. It may occur as the result of a trauma, a severe burn, a serious infection, heatstroke, blood loss, or even poisoning. If untreated, the individual can suffer permanent organ damage or death.
Decreased blood flow can cause problems with the heart. The cause of shock-like trauma can make the pulse weak, rapid, or what medical practitioners call “thready.” The jugular veins may appear distended. If left untreated, the pulse can substantially weaken.
