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