Clinically, the shock can be characterized as vascular insufficiency (cardiovascular finally) over acute caused by hypovolemia (disproportion between vascular capacity and total blood volume). Tissue hypo perfusion shock is conditioned by consecutive, absolute or relative hypoxia with cellular metabolism and cellular functional disorders that cause organ damage initially reversible and then irreversible.
Diagnosis and Treatment
A history and physical exam will be performed. Tests will be done to determine the cause of the shock.
Therapy is aimed at reversing the cause of the shock, and elevating the blood pressure. The following are used to raise the blood pressure: intravenous fluids, pressors (dopamine, norepinephrine, phenylephrine), and/or blood transfusions. ...
