PLAY
Respiratory Shock
Trauma to the respiratory tract (trachea, lungs) that causes a reduction of oxygen and carbon dioxide exchange. Body cells cannot receive enough oxygen.
Neurogenic Shock
Injury or trauma to the nervous system (spinal cord, brain). Nerve impulse to blood vessels impaired, blood vessels remain dilated and blood pressure decreases.
Cardiogenic Shock
Myocardial Infarction with damage to heart muscle; heart unable to pump effectively. Inadequate cardiac output. Body cells do not receive enough oxygen.
Hemorrhagic Shock
Severe bleeding or loss of body fluid from trauma, burns, surgery, or dehydration from severe nausea and vomiting. Blood pressure decreases, thus blood flow is reduced to cells, tissue, and organs.
Anaphylactic Shock
Results from reaction to substance to which patient is hypersensitive or allergic (allergen extracts, bee sting, medication, food). Outpouring of histamine results in dilation of blood vessels throughout the body.
Metabolic Shock
Body's homeostasis impaired; acid-base balance disturbed (diabetic coma or insulin shock); body fluids unbalanced.
Psychogenic Shock
Shock caused by overwhelming emotional factors. Sudden dilation of blood vessels results in fainting because of lack of blood supply to the brain.
Septic Shock
An acute infection, usually systemic, that overwhelms the body (toxic shock symdrome). Poisonous substances accumulate in bloodstream and blood pressure decreases, impairing blood flow to cells, tissues, and organs.
