Emt Terms In Chapter 10: Shock

Front 1

The force or resistance against which the heart pumps.

Back 1

afterload

Front 2

An extreme, life-threatening systemic allergic reaction that may include shock and respiratory failure.

Back 2

anaphylaxis (anaphylactic shock)

Front 3

A swelling or enlargement of part of a blood vessel, resulting from weakening of the vessel wall.

Back 3

aneurysm

Front 4

The part of the nervous system that regulates involuntary functions, such as heart rate, blood pressure, digestion, and sweating.

Back 4

autonomic nervous system

Front 5

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.

Back 5

cardiogenic shock

Front 6

The early stage of shock, in which the body can still compensate for blood loss.

Back 6

compensated shock

Front 7

A bluish gray skin color that is caused by a reduced level of oxygen in the blood.

Back 7

cyanosis

Front 8

The late stage of shock when blood pressure is falling.

Back 8

decompensated shock

Front 9

Loss of water from the tissues of the body.

Back 9

dehydration

Front 10

A condition that occurs when there is widespread dilation of the small arterioles, small venules, or both.

Back 10

distributive shock

Front 11

The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.

Back 11

edema

Front 12

A balance of all systems of the body.

Back 12

homeostasis

Front 13

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.

Back 13

hypothermia

Front 14

A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion.

Back 14

hypovolemic shock

Front 15

The final stage of shock, resulting in death.

Back 15

irreversible shock

Front 16

The ability of the heart muscle to contract.

Back 16

myocardial contractility

Front 17

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.

Back 17

neurogenic shock

Front 18

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.

Back 18

obstructive shock

Front 19

Circulation of blood within an organ or tissue in adequate amounts to meet current needs of the cells.

Back 19

perfusion

Front 20

The precontraction pressure in the heart as the volume of blood builds up.

Back 20

preload

Front 21

Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).

Back 21

psychogenic shock

Front 22

Developing a sensitivity to a substance that initially caused no allergic reaction.

Back 22

sensitization

Front 23

Shock caused by severe infection, usually a bacterial infection.

Back 23

septic shock

Front 24

A condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion.

Back 24

shock

Front 25

Muscles arranged in circles that are able to decrease the diameter of tubes. Examples are found within the rectum, bladder, and blood vessels.

Back 25

sphincters

Front 26

A fainting spell or transient loss of consciousness, often caused by an interruption of blood flow to the brain.

Back 26

syncope
