Autonomic nervous system
The part of the nervous system that regulates involuntary activities of the body, such as heart rate, blood pressure, and digestion of food
Cardiac Tamponade
Compression of the heart as the result of build up of blood or other fluid in the pericardial sac, leading to decreased cardiac output
cardiogenic shock
A state in which is 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
Compensated shock
The early stage of shock, in which the body can still compensate for blood loss
Cyanosis
A blue skin discoloration that is caused by a reduced level of oxygen in the blood
Decompensated shock
The late stage of shock when blood pressure is falling
Dehydration
Loss of water from the tissues of the body
Distributive shock
A condition that occurs when there is widespread dilation of the small artery arterioles, small venules, or both
Edema
The process of abnormally large amounts of fluid between cells in the body tissues, causing swelling of the affected area
Homeostasis
A balance of all systems of the body
Hypothermia
A condition in which the internal body temperature falls below 95°F
Hypovolemic shock
