Occurs when chemicals are released into the bloodstream to fight infection-triggers the inflammatory response throughout the body causing massive vasodilation. Common causes: UTI's, Pneumonia. Commonly acquired by very old/very young, weakened immune systems, malnourished, drug and alcohol abuse, wounds or injuries. Can also be hospital acquired by previous overuse of antibiotics, prescence of invasive lines, exposure to drug resistant bacteria, Ill patients, Urosepsis

Anaphylactic

This type of distributive shock is a severe allergic reaction. There is an antigen-antibody reaction that causes the release of histamine or bradykinin that then causes massive vasodilation, capillary permeability and vascular collapse. Caused by allergens that are inhaled, ingested contacted or introduced into the body via injections. Hives or Urticaria, rash, facial swelling, high pitched stridor.

Neurogenic

This type of distributive shock is where there is a loss of sympathetic tone which prevents constriction of blood vessels casing massive vasodilation. Can be caused by spinal anesthesia, lack of glucose, spinal shock, depressant medications, spinal cord injury. Lack of sympathetic nervous system response. S/S is hypotension and BRADYcardia.

Obstructive

This type of shock is blockage in the heart or major vessels which causes a decrease in cardiac output and tissue perfusion. Causes: Pulmonary embolism, Tension pneumothorax, Cardiac tamponade, Aoritc dissection. More common in trauma.

Hypovolemic shock

This type of shock is decreased intravascular volume. (Dehydration) is a decrease in the volume of blood in the body: Caused by Blood loss or fluid loss of some kind. Vomiting, diarrhea, profuse sweating, burns, diuretics, weeping, NPO status.

Cardiogenic shock

This type of shock occurs when the heart's ability to contract and pump blood is impaired and there is an inadequate supply of oxygen to the heart and tissues. Common causes: CHF, MI, HF, Cardiomyopathy (any heart disease) Dysrhythmias, SVT (Supra Ventricular Tachycardia)

Distrubutive shock

This type of shock results from EXCESSIVE VASODILATION and increased permeability causing impaired distribution of blood flow: Vital organs not getting blood, Pooling of blood. Three types: Septic Anaphylactic Neurogenic
