Oligemia

Oligemia is a condition characterized by insufficient volume of circulating blood in the body's vascular system. In other words, oligemia means hypovolemia.

In oligemia, circulating blood volume decreases due to loss of fluid or blood. This can happen for a variety of reasons: heavy bleeding, vomiting, diarrhea, dehydration due to heat or fever, burns. Oligemia also develops during shock conditions, for example, during traumatic, burn, hemorrhagic shock.

The main symptoms of oligemia: weakness, dizziness, tachycardia, decreased blood pressure, pale and cold skin, fainting. In severe cases, loss of consciousness and acute renal and liver failure are possible.

Treatment of oligemia consists of restoring the volume of circulating blood using intravenous infusions of crystalloid or colloid solutions, transfusion of blood or its components. It is also necessary to eliminate the cause of blood loss or dehydration. With timely and adequate treatment, the prognosis for oligemia is most often favorable.

Oligemia is a term that refers to a condition of the body in which there is a decrease in circulating blood volume against the background of a drop in circulation. The main cause of this pathological condition is a decrease in the amount of plasma due to hypoproteinemia. Also, the culprit of oligemia may be a decrease in blood volume, which occurs due to the presence of extensive hemorrhagic lesions of blood vessels or interstitial hemorrhages.
