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]
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]
Heart failure is usually associated with a volume overloaded state. Therefore, those with evidence of fluid overload should be treated initially with intravenous loop diuretics. In the absence of symptomatic low blood pressure intravenous nitroglycerin is often used in addition to diuretic therapy to improve congestive symptoms. [8]
An imbalance can cause fluid overload in the spaces between cells or tissues, ... Fluid retention can be a symptom of underlying conditions such as kidney disease, heart failure and liver disease ...
Symptoms and signs are varied and unpredictable, and result from fluid overload and disturbed electrolyte balance and hyponatremia. Treatment is largely supportive and relies on removal of the underlying cause, and organ and physiological support. Pre-operative prevention strategies are extremely important.
The thinking is that the fluid overload can help mitigate the negative effects of dehydration on performance—including fatigue, cramps, a higher heart rate, and more—which can start as soon as ...
This can be done with electrocardiogram, echocardiogram, measurement of cardiac enzymes, etc. Other causes of pulmonary edema that require rapid intervention and should be considered first include fluid overload, brain injury, and anaphylaxis. If when considering these differentials, there is no evidence for administration of excessive fluids ...
