Hypovolemic shock is a sudden, severe drop in the body's total fluid volume. This type of shock happens in four stages. Multiple organ failure occurs because the heart cannot pump a sufficient amount of blood and other fluids through the body. Children and older adults have the highest risk of developing this life-threatening condition, but it can affect people of any age. Recognizing hypovolemic shock quickly and getting emergency medical treatment is essential to avoiding long-term damage or death.
The circulatory system contains blood and fluids that carry oxygen, nutrients, and other components to tissues and organs. Blood also carries waste products to that get broken down or excreted from the body. The exchange of oxygen and carbon dioxide in the lungs depends on the circulating fluids pumped by the heart. When circulating blood volume is too low to maintain circulation, blood pressure drops rapidly and organs begin shutting down. Brain damage is possible after only two minutes without oxygen, so it is vital to treat hypovolemic shock immediately.
