  1. anaphylactic shock
    -- Severe shock caused by an allergic reaction.
  2. aNaphylaxis -
    - An extreme, possibly life-threatening systemic allergic reaction that may include shock and respiratory failure.
  3. aneurysm -
    - A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
  4. autonomic nervous system -
    - The part of the nervous system that regulates functions, such as digestion and sweating, that are not controlled voluntarily.
  5. cardiogenic shock -
    - A state in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart. It can be a severe complication of a large acute myocardial infarction, as well as other conditions.
  6. compensated shock -
    - The early stage of shock, in which the body can still compensate for blood loss
  7. cyanosis -
    - A bluish-gray skin color that is caused by reduced levels of oxygen in the blood.
  8. decompensated shock -
    - The late stage of shock, when blood pressure is falling.
  9. dehydration -
    - A state in which fluid losses are greater than fluid intake into the body, leading to shock and death if untreated.
  10. edema -
    - The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
  11. homeostasis -
    - A balance of all systems of the body
  12. hypothermia -
    - A condition in which the internal body temperature falls below 95 degrees F (35 degrees C) after exposure to a cold environment.
  13. hypovolemic shock -
    - A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion.
  14. irreversible shock -
    - The final stage of shock, resulting in death.
  15. neurogenic shock -
    - Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in spinal cord injuries.
  16. perfusion -
    - The circulation of oxygenated blood within an organ or tissue in adequate amounts to meet the cells'' current needs.
  17. psychogenic shock -
    - Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
  18. sensitization -
    - Developing a sensitivity to a substance that initially caused no allergic reaction.
  19. septic shock -
    - Shock caused by severe infection, usually a bacterial infection.
  20. shock -
    - A condition in which the circulatory system fails to provide sufficient circulation so that every body part can perform its function; also called hypoperfusion.
  21. sphincters -
    - Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening.
  22. syncope -
    - Fainting spell or transient loss of consciousness.
