Shock is the state of insufficient blood flow to the tissues of the body as a result of problems with the circulatory system.Initial symptoms of shock may include weakness, tachycardia, hyperventilation, sweating, anxiety, and increased thirst. [1]
Cardiogenic shock is most commonly precipitated by a heart attack. [4] Treatment of cardiogenic shock depends on the cause with the initial goals to improve blood flow to the body. If cardiogenic shock is due to a heart attack, attempts to open the heart's arteries may help. Certain medications, such as dobutamine and milrinone, improve the ...
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [ 1 ] [ 2 ] It can be caused by severe dehydration or blood loss . [ 3 ] [ 2 ] Hypovolemic shock is a medical emergency ; if left untreated, the insufficient blood flow can cause damage to organs , leading to ...
In the cases of cardiogenic shock resulting from heart failure or acute hemorrhagic shock caused by a large volume of blood loss, the body constricts peripheral vessels to reverse the low arterial pressure that causes inadequate tissue perfusion. [22] With vasodilatory shock, it is difficult for the peripheral vascular smooth muscle to ...
The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease , the additional workload can result in myocardial infarction and/or acute heart failure , which ultimately may lead to a ...
A second main category of shock is cardiogenic shock, cardio - genic means produced by the heart, right? So this is when something happens to the heart such that now it can’t pump enough blood to the body’s tissues. The most common cause is acute myocardial infarction, or heart attack.
Obstructive shock is one of the four types of shock, caused by a physical obstruction in the flow of blood. [1] Obstruction can occur at the level of the great vessels or the heart itself. [ 2 ] Causes include pulmonary embolism , cardiac tamponade , and tension pneumothorax . [ 3 ]
Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.
