If the kidneys are getting enough blood to function well they concentrate the urine in an effort to correct the low blood volume. In more severe cases they cannot make much urine because they are not getting enough blood flow.

What are the two major types of extracellular fluid?
hypovolemic shock and edema
What is particularly sensitive to injury during states of shock or cardiopulmonary arrest?
There are several organs that are particularly sensitive to injury during low perfusion states such as hypovolemic shock or cardiopulmonary arrest. These organs are the ones that also tend to have high perfusion rates, such as the brain and kidneys.
What are the different kinds of seismic waves?
* Hypovolemic shock. The single most common cause of shock is blood volume loss, resulting from a serious wound or a severe burn leading to hypovolemic shock. * Cardiogenic shock is caused by the failure of the heart to pump effectively. This can be due to damage to the heart muscle, most often from a large myocardial infarction. Other causes of cardiogenic shock include arrhythmias, or cardiac valve problems. * Distributive shock. As in hypovolemic shock there is an insufficient volume of blood. This form of relative hypovolaemia is the result of dilation of bloodvessels. Examples of this form of shock are: * Septic shock is caused by overwhelming infection leading to vasodilation. It is treated by antibiotics, fluid replacement, and vasoconstrictors. * Acute adrenal insufficiency is not infrequently the result of discontinuing corticosteroid treatment without tapering the dosage. * Less commonly severe anaphylactic reactions may cause anaphylactic shock as allergens trigger widespread vasodilation and movement of fluid out of the blood into the tissues. * The rarest cause of shock is acute spinal cord injury leading to neurogenic shock. Neurogenic shock is caused by the sudden loss of the sympathetic nervous system signals to the smooth muscle in vessel walls. Without this constant stimulation the vessels relax resulting in a sudden decrease in peripheral vascular resistance and decreased blood pressure. * Obstructive shock. Hereby the flow of blood is obstructed. Several conditions result in this form of shock. * Cardiac tamponade, in which blood in the pericardium prevents inflow of blood into the heart (venous return). Or constrictive pericarditis which has the same effect. * Pneumothorax. Through increased intrathoracic pressure bloodflow to the heart is prevented (venous return). * Pulmonary embolism is the result of a thromboembolic incident in bloodvessels of the lungs and hinders the return of blood to the heart.
How does dopamine increase urine output?
Used to treat hypotension in shock states that are not due to hypovolemia. (dopaminergic effect): dilates the renal and messenteric blood vessels, producing an increase in urine output.
What organ is the last to perfuse during shock?
Heart
Why is someone's skin cold and clammy in hypovolemic shock?
During shock, blood is conserved for the vital organs, and blood flow to the skin is decreased. This makes the skin feel cold and clammy.
How does the body compensate for hypovolemic shock?
early sign of hypovolemic shock
What is a psychogenic shock?
a type of hypovolemic shock
What cause hypovolemic shock?
Hypovolemic shock is primarily caused by poor perfusion, usually from excess blood or fluid loss from the body. Hypovolemic shock is the most common type of pre-hospital shock often resulting from moderate or severe trauma.
What is the pathophysiology of shock?
Cardiogenic, hypovolemic, or septic shock?
What happens to your liver during shock?
Hypovolemic shock markedly decreases total liver blood flow by a reduction in portal venous blood flow.
Diagnosis of hypervolemic shock?
I believe you are thinking of HYPOvolemic shock, which is the result of a loss of blood volume like after an injury. One would expect to see a very low blood pressure, a rapid pulse, and a decreased body temperature. Shock can not be caused by HYPERvolemia.
Is most common form of shock hypovolemic shock?
only that form of shock caused by large scale loss of blood.
