chapter 13 - shock & pathophysiology Flashcards
The part of the nervous system that controls the involuntary activities of the body such as the heart rate, blood pressure and digestion of food
autonomic nervous system
A blue skin discoloration that is caused by a reduced level of oxygen in the blood
cyanosis
The ability of the heart muscle to contract
myocardial contractility
Developing a sensitivity to a substance that initially caused no allergic reaction
Sensitization
A blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow
pulmonary embolism
A collection of fluid between the pericardial sac and the myocardium
pericardial effusion
The late stage of shock when blood pressure is falling
Decompensated shock
Muscles that encircle and, by contracting, constrict a duct, tube or opening
Sphincters
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
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
A state in which not enough oxygen is delivered to the tissues of the body, caused by a low output of blood from the heart
Cardiogenic shock
A condition in which the internal body temperature falls below 95 degrees F (35 degrees C)
Hypothermia
An extreme, life-threatening, systemic allergic reaction that may include shock and respiratory failure
Anaphylaxis
Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope)
Psychogenic shock
A balance of all systems of the body
Homeostasis
