Similar aspects of the endocrine and nervous systems are also located within major arteries, responding to changes in the cardiovascular system during hypovolemic shock. When baroreceptors sense there has been a fluid loss and that blood pressure has decreased, a “sympathetic response” throughout the body where nerve impulses cause the heart rate to increase to attempt to compensate for a decrease in oxygen circulating throughout the body (Tortura 782). An increase in the heart also causes respiration to increase in speed as well to keep up with demand of oxygen (Red Cross 170). This increase in circulation and respiration is also effected by the restriction of blood flow to the brain, heart, and sometimes kidneys, as mentioned previously.

However, when blood pressure drops and these feedback systems are not effective in raising it back up, the body then enters into the decompensated phase. Decompensate shock is life threatening, as the circulation of blood and transfer of oxygen is slowed down to a point where, when prolonged, gradual tissue damage from cells dying can occur. This phase can also easily lead into the final stage, irreversible shock, where “the depressed cardiac output can no longer be reversed with volume-replacement therapies” (Wang 157). However, with early recognition of shock and proper care, the phase of compensated shock can be delayed or extended, so that life threatening conditions can be avoided.
Causes of hypovolemic shock and severe fluid loss occur in many different ways, however because the most common cause is of severe blood loss, it is best to first discuss types of hemorrhage and the care that follows. Severe hemorrhage is most often caused by a tear in a major artery or vein that are located deep below skin and muscle tissue (Red Cross 160). A tear can be result of an external wound or from damage to internal structures, both display different symptoms and require different
