The general bodily disturbance following a severe injury; an emotional or moral upset occasioned by some disturbing or unexpected experience; disruption of the circulation, which can upset all body functions: sometimes referred to as circulatory shock.<\/p>\n
Sudden and disturbing mental or physical impression also a state of collapse characterized by pale, cold, sweaty skin, rapid, weak, thready pulse, faintness, dizziness, and naused.<\/p>\n
A condition that results because the blood tends to pool in the blood vessels in the viscera depriving the brain of needed blood and oxygen. Usually follows some physical or emotional trauma.<\/p>\n
A state of weakness caused by illness or injury that suddenly reduces the blood pressure.<\/p>\n
Condition in which the peripheral blood flow is inadequate to return blood to the heart; decreased cardiac output causing poor tissue perfusion.<\/p>\n
A condition in which blood flow to the body\u2019s tissues is so dramatically reduced that blood-starved tissues can be severely damaged, possibly leading to collapse, fainting, coma, and death. Symptoms of shock include clammy, cold skin; paleness; rapid, weak breathing and pulse; dizziness; and weakness. Emergency medical help should be summoned immediately. Until help arrives, the victim should be wrapped in blankets (with hot water if possible) to maintain body temperature, laid prone on his or her back with feet slightly elevated, and calmly comforted and reassured. Bleeding should be stopped if possible and the breathing passages kept open. No food, drink, or drugs should be given. In a hospital, patients in shock are often given blood, fluids, and\/or medications intravenously, as well as oxygen, while the underlying problem is being treated. A danger in any severe injury or illness, shock can result from a variety of causes, including spinal-cord injury, injury involving great loss of blood, heart problems blocking the flow of blood or causing extremely low blood pressure, burns, dehydration from long-Standing diarrhea or vomiting, or poisons. Severe bacterial infection can result in septic shock syndrome, including toxic shock syndrome. A severe allergic reaction to an injected substance, such as a bee\u2019s venom or penicillin, is called anaphylactic shock.<\/p>\n
Abnormal body state associated with inadequate oxygen delivery to the metabolic apparatus of the cell (the mitochondrion). This can occur for many reasons, including hypovolemia, cardiac failure (cardiogenic shock), obstruction to blood flow (obstructive shock), and maldistribution of the blood flow (distributive shock). Shock is characterized by reduced cardiac output, circulatory insufficiency, rapid heartbeat, and pallor. Low blood pressure, though classically associated with shock, is a late sign, especially in children. Treatment is primarily that of the underlying condition. Intravenous fluid therapy helps most patients, at least initially.<\/p>\n
Collapse of the circulatory system, resulting in a dramatic decrease in blood pressure. Symptoms include pale, cold, moist skin; weakness; fast pulse; and shallow breathing. The victim may also be thirsty, nauseous, and void very little urine. Shock may result from trauma, heavy bleeding, severe bums, or illness.<\/p>\n
The condition associated with circulatory collapse, when the arterial blood pressure is too low to maintain an adequate supply of blood to the tissues. The patient has a cold sweaty pallid skin, a weak rapid pulse, irregular breathing, dry mouth, dilated pupils, and a reduced flow of urine. Shock may be due to a decrease in the volume of blood, as occurs after internal or external ‘hemorrhage, dehydration, bums, or severe vomiting or diarrhea. It may be caused by reduced activity of the heart, as in coronary thrombosis, myocardial infarction, or pulmonary embolism. It may also be due to widespread dilation of the veins so that there is insufficient blood to fill them. This may be caused by the presence of bacteria in the bloodstream Ibacteremic shock), a severe allergic reaction {anaphylactic shock: see anaphylaxis), overdosage with such drugs as narcotics or barbiturates, or the emotional shock due to a personal tragedy or disaster (neurogenic shock). Sometimes shock may result from a combination of any of these causes, as in ‘peritonitis. The treatment of shock is determined by the cause.<\/p>\n
In lay usage this refers to fright, horror or any acute distress. Medically it means a state of acute circulatory failure in which the heart’s output of blood is inadequate to provide normal perfusion of the major organs. It is accompanied by a fall in arterial blood pressure and is characterized by systemic arterial hypotension (arterial blood pressure less than 80), sweating and signs of vasoconstriction (for example, pallor, cyanosis, a cold clammy skin and a low-volume pulse). These signs may be associated with clinical evidence of poor blood supply to body tissues (poor perfusion), for example to the brain and kidneys, leading to mental apathy, confusion or restlessness and oliguria.<\/p>\n
A clinical syndrome marked by inadequate perfusion and oxygenation of cells, tissues, and organs, usually as a result of marginal or markedly lowered blood pressure.<\/p>\n
A condition in which some body organs do not get enough oxygenated blood.<\/p>\n
A condition that may accompany any serious injury or illness, in which the heart fails to circulate blood adequately to the vital organs.<\/p>\n
Hypovolemia is a medical condition characterized by an insufficient volume of blood circulating within the body to meet its essential requirements. This condition, commonly referred to as shock, can be triggered by various factors, including certain diseases, severe physical trauma, or significant blood loss.<\/p>\n
An alarming decrease in blood circulation across bodily tissues, a condition that can arise due to severe injury or illness. This type of shock is a physiological response, separate from the emotional distress that might ensue after a traumatic event.<\/p>\n
In the majority of instances, diminished blood pressure plays a pivotal role in instigating shock and is also one of its primary characteristics. Shock can arise in various situations where there’s a reduction in blood volume, abnormal dilation of blood vessels, weakened cardiac function, hindered blood flow, or a combination of these factors. Potential causes of shock encompass severe bleeding or burns, continuous vomiting or diarrhea, myocardial infarction (heart attack), pulmonary embolism (a blood clot in the lung), peritonitis (inflammation of the abdominal lining), and certain types of poisoning.<\/p>\n
Indications encompass swift, superficial respiration; chilly, moist skin; a swift, feeble heartbeat; feelings of lightheadedness; debilitation; and loss of consciousness. If not addressed, shock can jeopardize the delivery of oxygen to critical organs like the brain, ultimately resulting in collapse, unconsciousness, and fatality.<\/p>\n
Urgent medical intervention is required. This entails administering fluids through an intravenous infusion, providing a blood transfusion, implementing oxygen therapy, and, if needed for pain management, utilizing morphine or potent analgesic medications. Subsequent treatment strategies hinge on the root cause of the condition.<\/p>\n
A term with two distinct meanings, depending on whether the cause is emotional or physical. However, the word is commonly employed in the emotional context, leading to confusion.<\/p>\n
