Shock is a life-threatening condition resulting from a lack of blood flow throughout the body, often characterized by low blood pressure. Shock can be categorized as obstructive, cardiogenic, distributive, septic, anaphylactic and hypovolemic. The type of shock that is caused on by severe bleeding is hypovolemic. Hypovolemic shock results from a lack of volume of blood flow throughout the body.
Shock can be caused from internal or external loss of blood from an injury. In external bleeding, the blood is easily seen versus internal bleeding, when relying on signs and symptoms is the best indicator. There are 3 stages of shock. The first stage is compensated, the second is decompensated and the third is irreversible.
