PATHOLOGY

Detailed explanation-1: -The most common cause of hypovolemic shock is blood loss when a major blood vessel bursts or when you’re seriously injured. This is called hemorrhagic shock. You can also get it from heavy bleeding related to pregnancy, from burns, or even from severe vomiting and diarrhea.

Detailed explanation-2: -Hypovolemic shock occurs when there is a decreased intravascular volume to the point of cardiovascular compromise. The hypovolemic shock could be due to severe dehydration through a variety of mechanisms or from blood loss.

Detailed explanation-3: -Patients with massive hemorrhage may experience conditions ranging from severe hypovolemia, in which blood volume decreases with no changes in hemoglobin concentration, to isovolemic anemia, in which extreme decreases in hemoglobin concentration occur with normal or even increased blood volume.
