volume overload

Pathophysiology A state of actual–eg, due to excess administration or ingestion, or functional–eg, due to CHF–fluid excess. Cf Dehydration.

volume overload

An excess of blood or body fluids in the circulation or extracellular tissues. It is usually caused by transfusions or excessive fluid infusions that increase the venous pressure, esp. in patients with heart disease, and it can result in heart failure, pulmonary edema, and cyanosis.
Synonym: circulatory overload; fluid overload; hypervolemia

These findings could suggest that uncorrected metabolic acidosis results in intradialytic BP rise in hemodialysis patients, due to its relationship with sodium imbalance and volume overload in these patients, even if clinically non-apparent, apart from its role in the increased ionized plasma calcium, which is already associated with hypertension [41].
D-shaped left ventricle evidenced during systole (particularly end-systole) suggests RV pressure overload, whereas a D-shaped ventricle in diastole suggests RV volume overload. Septal flattening is best appreciated in the short-axis view at the level of the basal or mid-left ventricle.
Chronic heart failure with pulmonary venous hypertension and volume overload brings along characteristic radio-morphological changes in thoracic imaging.
Volume removal by ultrafiltration has been shown to increase cardiac output in patients with refractory congestive heart failure [75] and to improve ejection fraction in volume overloaded patients with end-stage renal disease [16].
The presence of a positive HJR on discharge of patients hospitalized with decompensated systolic HF correlates well with objective markers of volume overload and is an independent predictor of 6-month mortality.
A system trying to improve outcomes for congestive heart failure will be frustrated if its records are littered with diagnoses of "volume overload" and do not distinguish between acute and chronic or systolic and diastolic cases.
* Monitor BP and cardiovascular system for volume overload, left ventricular hypertrophy/dilatation.
Causes of isotonic fluid volume overload include excessive administration of fluids and excessive irrigation of body cavities (enemas, peritoneal dialysis, gastric lavage, etc.).
Thus, while the immediate issue is resolved, colloids can contribute to fluid volume overload in the following days.
Background: Pulmonary artery banding is a palliative surgical procedure used as a staged-approach to operative correction of congenital heart defects leading to right ventricular volume overload and pulmonary hypertension.
Increased right ventricle pressures and volume overload deviate interventricular septum to the left and decrease left ventricular filling and this could cause diastolic dysfunction (4).
Complications of HUS include severe anemia from microangiopathic hemolytic anemia, volume overload and hypertension from anuria or oliguria, hyperkalemia from hemolysis of erythrocytes in combination with renal insufficiency, and various other electrolyte abnormalities.
