Chapter 13 Shock Flashcards
The force or resistance against which the heart pumps
Afterload
Severe shock caused by an allergic reaction
Anaphylactic shock
Extreme life-threatening systemic allergic reaction that may include shock and respiratory failure
Anaphylaxis
The swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall
Aneurysm
The part of the nervous system regulates, involuntary activities of the body, such as heart rate, blood pressure and digestion of food
Autonomic nervous system
Compression of the heart as a result of buildup of blood, or other fluid in the pericardial sac, leading to decreased cardiac output
Cardiac tamponade
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 blue skin discoloration that is caused by reduced level of oxygen in the blood, although paleness, or a decrease in blood flow can be difficult to detect and dark skin people. It may be observed by examining mucous membranes inside the inner lower eyelid and capillary refill on general observation the patient may appear action or gray
Cyanosis
Complete state 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 a widespread dilation of the small arterials, small venules, or both
 Distributive shock
The process 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 Fahrenheit, 35°C
Hypothermia
A condition in which low blood volume to the massive internal or external bleeding or extensive loss of body water results in inadequate perfusion
Hypovolemic shock
A condition defined by the inability to successfully achieve resuscitation, regardless of the methods employed
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 bodies tissues
Obstructive shock
The flow of blood through the body, tissues and vessels
Perfusion
A collection of fluid between the pericardial, sac and myocardium
Pericardial effusion
The pre-contraction pressure in the heart as the volume of blood built-up
Preload
Shock caused by a sudden temporary reduction in blood supply to the brain that causes fainting (syncope)
 Psychogenic shock
A blood clot that breaks off from a large vein and travels to the blood vessels of the lungs, causing obstruction of blood flow
Pulmonary embolism
The difference between the systolic and diastolic pressure’s
Pulse pressure
Developing a sensitivity to a substance that initially cause 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 maintain normal cellular function, also called hypoperfusion
Shock
Muscles that in circle and buy contracting, construct a duct, tube or opening
Sphincters
A fainting spell or transient loss of consciousness
Syncope
