Severe shock caused by allergic reactions.
anaphylactic shock
A condition in which low blood volume, due to either massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion.
hypovolemic shock
Fainting spell or transient loss of consciousness, often caused by an interruption of blood flow to the brain.
syncope
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
Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
psychogenic shock
A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
aneurysm
Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in spinal cord injuries.
neurogenic shock
A condition that develops when the circulatory system is not able to deliver sufficient blood to body organs, resulting in organ failure and eventual death if untreated.
shock
The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
edema
Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening.
sphincters
An extreme, possibly life-threatening systemic allergic reaction that may include shock and respiratory failure.
anaphylaxis
Bluish-gray skin color that is caused by reduced oxygen levels in the blood.
cyanosis
Shock caused by severe bacterial infection.
septic shock
A state in which fluid losses are greater than fluid intake into the body, leading to shock and death if untreated.
dehydration
The part of the nervous system that regulates functions, such as digestion and sweating, that are not controlled voluntarily.
autonomic nervous system
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.
hypothermia
The early stage of shock, in which the body can still compensate for blood loss.
compensated shock
Developing a sensitivity to a substance that initially caused no allergic reaction.
sensitization
The late stage of shock, when blood pressure is falling.
decompensated shock
The most posterior portion of the cranium.
occiput
Shortness of breath or difficulty breathing.
dyspnea
The final stage of shock, resulting in death.
irreversible shock
The circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs.
perfusion
