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]
Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.
High blood pressure (hypertension, which is when the systolic pressure is between 130 and 139 or diastolic pressure is between 80 and 89) can raise the risk of heart attack and stroke if left ...
Volume overload refers to the state of one of the chambers of the heart in which too large a volume of blood exists within it for it to function efficiently. Ventricular volume overload is approximately equivalent to an excessively high preload. It is a cause of cardiac failure. [1]
Blood pressure is a crucial indicator of our overall health and well-being. Prolonged high blood pressure, or hypertension, can lead to severe complications such as heart disease, stroke, kidney ...
Intravascular volume depletion is divided into three types based on the blood sodium level: Isonatremic (normal blood sodium levels) Example: a child with diarrhea, because both water and sodium are lost in diarrhea. Hyponatremic (abnormally low blood sodium levels). Example: a child with diarrhea who has been given tap water to replete ...
CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP), [1] although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium. CVP and ...
