EMS Chapter 10 Shock

Emergency Care & Transp. 10th Edition 2011 Jones & Bartlett

afterload The force or resistance against which the heart pumps.
anaphylaxis (anaphylactic shock) An extreme, life-threatening systemic allergic reaction that may include shock and respiratory failure.
aneurysm A swelling or enlargement of part of a blood vessel, resulting from weakening of the vessel wall.
autonomic nervous system The part of the nervous system that regulates involuntary functions, such as heart rate, blood pressure, digestion, and sweating.
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.
compensated shock The early stage of shock, in which the body can still compensate for blood loss.
cyanosis A bluish gray skin color that is caused by a reduced level of oxygen in the blood.
decompensated shock The late stage of shock when blood pressure is falling.
dehydration Loss of water from the tissues of the body.
distributive shock A condition that occurs when there is widespread dilation of the small arterioles, small venules, or both.
edema The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
homeostasis A balance of all systems of the body.
hypothermia A condition in which the internal body temperature falls below 95°F (35°C), usually as a result of prolonged exposure to cool or freezing temperatures.
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.
irreversible shock The final stage of shock, resulting in death.
myocardial contractility The ability of the heart muscle to contract.
neurogenic shock Circulatory 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.
obstructive shock Shock that occurs when there is a block to blood flow in the heart or great vessels, causing an insufficient blood supply to the body's tissues.
perfusion Circulation of blood within an organ or tissue in adequate amounts to meet current needs of the cells.
preload The precontraction pressure in the heart as the volume of blood builds up.
psychogenic shock Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
sensitization Developing a sensitivity to a substance that initially caused no allergic reaction.
septic shock Shock caused by severe infection, usually a bacterial infection.
shock A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion.
sphincters Muscles arranged in circles that are able to decrease the diameter of tubes. Examples are found within the rectum, bladder, and blood vessels.
syncope A fainting spell or transient loss of consciousness, often caused by an interruption of blood flow to the brain.
