Hypervolemia, also known as fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in ...
In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]
Heart failure, particularly with reduced ejection fraction (HFrEF), is a major cause of morbidity and mortality worldwide. Aldosterone, a hormone that promotes sodium retention and potassium excretion, plays a significant role in the pathophysiology of heart failure by contributing to fluid overload, myocardial fibrosis, and vascular damage.
Cardiogenic pulmonary edema is typically caused by either volume overload or impaired left ventricular function. As a result, pulmonary venous pressures rises from the normal average of 15 mmHg. [13] As the pulmonary venous pressure rises, these pressures overwhelm the barriers and fluid enters the alveoli when the pressure is above 25 mmHg. [14]
Fluid absorption leads to rapid volume expansion, which causes hypertension and reflex bradycardia. The oncotic pressure of blood will decrease as a result of the dilution of serum proteins, and this coupled with hypertension will push fluid from the intra-vascular to the interstitial compartment causing pulmonary and cerebral edema.
An imbalance can cause fluid overload in the spaces between cells or tissues, which can lead to edema, per the National Institutes of Health. Edema refers to the swelling that happens when the ...
Intravascular volume overload can occur during surgery, if water rather than isotonic saline is used to wash the incision. It can also occur if there is inadequate urination, e.g. with certain kidney diseases.
