Failure of the blood vascular system to provide adequate circulation to the vital organs; circulatory collapse.
(shok) State of physiological collapse marked by a weak pulse, coldness, sweating and irregular breathing. Shock can result from (for example) blood loss, heart failure, allergic reaction or emotional trauma.
acute failure of the peripheral circulatory system due to alteration of circulatory control or loss of circulating fluid; marked by low blood pressure, body coldness, and rapid heartbeat. Spore (bacterial): a dehydrated life-stage of certain bacteria that is highly resistant to prolonged exposure to chemical disinfectants, ultraviolet (UV) light and high-energy radiation such as X-rays, as well as extremes in pH and temperature or drying conditions. Spore (fungal): the reproductive elements of fungi produced either sexually or asexually.
The sensory impression caused by an electrical current flow through the body.
A condition that occurs after the body has undergone severe injury that results in a shut down of the body's circulatory system.
physiological response to stress or injury.
A medical condition manifested by a decreased blood pressure, circulatory insufficiency, and a weakened pulse that can be life-threatening.
A condition in which body function is impaired because the volume of fluid circulating through the body is insufficient to maintain nominal metabolism. This may be caused by blood loss or by a disturbance in the function of the circulatory system.
A severe condition that disturbs the body. A person with diabetes can go into shock when the level of blood glucose (sugar) drops suddenly. See also: Insulin shock.
potentially fatal physiological reaction to a variety of conditions, including illness, injury, hemorrhage, and dehydration, usually characterized by marked loss of blood pressure, diminished blood circulation, and inadequate blood flow to the tissues
A disorder resulting from disruption of the circulation of the blood that can upset all body functions.
sudden and disturbing mental and/or physical state; i.e., cold; pale and sweaty skin; rapid, weak, and thready pulse; faintness; dizziness and nausea.
(pathology) bodily collapse or near collapse caused by inadequate oxygen delivery to the cells; characterized by reduced cardiac output and rapid heartbeat and circulatory insufficiency and pallor; "loss of blood is an important cause of shock"
a change in density over a distance which is on the scale of the consitutents of the flow
A stressed condition of the body caused by major trauma.
A collapse of the body's systems caused by a fall in the volume of circulating blood. The term can also refer to a temporary state of psychological overburdening.
Amend definition: A life-threatening condition in which the peripheral circulation fails either because of excess fluid or blood loss or because of loss of circulatory control.
Insufficient oxygen getting to where it is needed in the body. Can be caused by many things including loss of blood, allergic reactions, emotional response and damage to the spinal cord.
a generalized depression of all body functions which results in decreased blood flow.
the body's reaction when blood circulation fails; also called hypoperfusion
"Circulatory collapse," when blood pressure drops too low to maintain an adequate supply of blood to the body's tissues
When blood flow to the body's tissue is reduced due to severe injury, blood loss, or disease, and characterized by clammy, cold skin, weak pulse, and very low blood pressure.
A state of severe low blood pressure usually caused by severe sepsis or the acute loss of blood. Life-threatening.
State of cardiovascular collapse resulting in generalized tissue hypoperfusion and hypotension when compensatory mechanisms fail.
Life-threatening condition (usually) due to collapse of the circulatory system.
a dangerous reduction of blood flow throughout the body.
A physical state often caused by severe injury, and characterized by depressed physical response (blood pressure, heart rate, etc.).
The life-threatening systemic reaction to inadequate perfusion of the tissue with oxygenated blood. Not the same as an autonomic reaction.
vital organs lack oxygen due to: breathing problems bleeding burns head or spine injuries heart attack allergies strong emotions shock is present with injury and illness, and can lead to death always treat for shock
impaired body function due to blood loss or a disturbance in the circulatory system.
a state of inadequate tissue perfusion.
A reduced flow of blood throughout the body, usually caused by severe bleeding or a weak heart; without treatment, can lead to a collapse, coma, and death.
In medicine, shock is a critical condition brought on by a sudden drop in blood flow through the body. There is failure of the circulatory system to maintain adequate blood flow. This sharply curtails the delivery of oxygen and nutrients to vital organs. It also compromises the kidney and so curtails the removal of wastes from the body. Shock can be due to a number of different mechanisms including not enough blood volume (hypovolemic shock) and not enough output of blood by the heart (cardiogenic shock). The signs and symptoms of shock include low blood pressure (hypotension), overbreathing (hyperventilation), a weak rapid pulse, cold clammy grayish-bluish (cyanotic) skin, decreased urine flow (oliguria), and mental changes (a sense of great anxiety and foreboding, confusion and, sometimes, combativeness). See the entire definition of Shock
a condition characterized by the depression of mental and physical functioning, for example due to an injury or an allergic reaction.
A rapid and substantial drop in blood pressure caused by lowering of effective blood volume.
Severe injury, blood loss, or disease can cause the blood flow to the body's tissue to be reduced, and a person may then go into shock. The state is characterised by clammy, cold skin, a weak pulse, and very low blood pressure.
Not to be confused with fright, this is a serious psychological condition characterised by paleness, increased heart rate, cold extremities and a potentially altered state of consciousness. This could also be the result, for example, of sudden and severe blood loss. Contact your vet at once. Wrap your dog in a blanket and offer a warm drink.
This is a lack of blood in your cat's system, and could be fatal. A cat who goes into shock could display any of the following: panting, rapid or shallow breathing, inability to stand, enlarged pupils, cold ears and paws and very pale gums. Contact your vet at once. Wrap your cat in a blanket.
insufficient blood in vital parts of the body which temporarily stop functioning, if untreated can lead to brain damage or death; often a reaction to injury
Muscular spasm caused by charge flow.
inadequate delivery of blood to the body's organs.
A force to which an object is subjected that disturbs the object's stability, causing an imbalance of equilibrium. Shock is often isolated in conjunction with vibration to stabilize an object's equilibrium.
A condition in which the oxygen supply to the organs and the return of blood to the heart are disturbed. It can be life-threatening.
a condition of acute peripheral circulatory failure due to derangement of circulatory control or loss of circulating fluid. It is characterized by hypotension, coldness of the skin, rapid heart rate (usually), and often anxiety. Anaphylactic s., the violent onset of symptoms produced on second exposure to allergenic protein in an anaphylactic individual.
A dangerous reduction in blood flow to body tissues.
An acute peripheral circulatory failure due to decreased cardiac output, poor circulatory control (heart ineffective in pumping) or loss of circulating fluid. It is marked by hypotension, tachycardia, coldness of skin and anxiety.
Shock is a short-term state of body weakness that usually happens after an accident of injury, caused when there is an insufficient supply of oxygen t
A generally temporary massive physiological reaction to severe physical or emotional trauma, usually characterized by marked loss of blood pressure and depression of vital processes.
Shock is a serious medical condition where the tissue perfusion is insufficient to meet demand for oxygen and nutrients. This hypoperfusion state is a life-threatening medical emergency and one of the leading causes of death in a critically ill person. This primary cause may lead to many other medical emergencies, such as hypoxia or cardiac arrest.
