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
