Chapter 13 Flashcards
The force or resistance against which the heart pumps.
Afterload
Severe shock caused by an allergic reaction
Anaphylactic Shock
An extreme, life-threatening, systemic allergic reaction that may include shock and respiratory failure.
Anaphylaxis
A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
Aneurysm
The part of the nervous system that regulates involuntary activities of the body, such as heart rate, blood pressure, and digestion of food.
Autonomic Nervous System
Compression of the heart as the 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 infraction, as well as other conditions.
Cardiogenic Shock
The early stage of shock, in which the body can still compensate for blood loss.
Compensated Shock
The late stage of shock when blood pressure is failing.
Decompensated Shock
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 Degrees Fahrenheit or (35) Celsius.
Hypothermia
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.
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 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 tissue.
Obstructive Shock
The flow of blood through body tissues and vessels.
Perfusion
A collection of fluid between the pericardial sac and the myocardium.
Pericardial Effusion
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
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
The difference between the systolic and diastolic pressures.
Pulse Pressure
