  1. The ability of the heart muscle to contract.
    Myocardial contractility
  2. A fainting spell or transient loss of consciousness, often caused by an interruption of blood flow to the brain.
    Syncope
  3. An extreme, life-threatening systemic allergic reaction that may include shock and respiratory failure.
    Anaphylaxis (anaphylactic shock)
  4. A stat in which not enough O2 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.
    Cardiogenic shock
  5. A balance of all systems of the body.
    Homeostasis
  6. Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
    Psychogenic shock
  7. The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
    Edema
  8. The part of the nervous system that regulates involuntary functions, such as heart rate. blood pressure, digestion, and sweating.
    Autonomic nervous system
  9. Shock that occurs when there is a block to blood flow in the heart or great vessels, causing an insufficinet blood supply to the body's tissues.
    Obstructive shock
  10. Circulation of blood within an organ or tissue in adequate amounts to meet the current needs of the cells.
    Perfusion
  11. A bluish gray skin color that is caused by a reduced level of O2 in the blood.
    Cyanosis
  12. The force or resistance against which the heart pumps.
    Afterload
  13. A swelling or enlargement of part of a blood vessel, resulting from weakening of the vessel wall.
    Aneurysm
  14. The final stage of shock, resulting in death.
    Irreversible shock
  15. Developing a sensitivity to a substance that initially caused no allergic reaction.
    Sensitization
  16. Loss of water from the tissues of the body.
    Dehydration
  17. The late stage of shock when blood pressure is falling.
    Decompensated shock
  18. A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water results in inadequate perfusion.
    Hypovolemic shock
  19. Cirulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in patients with spinal cord injuries.
    Neurogenic shock
  20. a condition that occurs when there is widespread dilation of small arterioles, small venules, or both.
    Distributive shock
  21. The early stage of shock in which the body can still compensate for blood loss.
    Compensated shock
  22. Muscles arranged in circles that are able to decrease the diameter of tubes. Examples are found within the rectum. bladder. and blood vessels.
    Sphincters
  23. A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion.
    Shock
  24. The precontraction pressure in the heart as the volume of blood builds up.
    Preload
  25. Shock caused by severe infection, usually a bacterial infection.
    Septic shock
  26. A condition in which the internal body temp falls below 95 deg F (35 degrees C), usually as a result of prolonged exposure to cool or freezing temps.
    Hypothermia
