Volume.

Volume is the number of shares traded in a company's stock or in an entire market over a specified period, typically a day.

Unusual market activity, either higher or lower than average, is typically the result of some external event. But unusual activity in an individual stock reflects new information about that stock or the stock's sector.

On the other hand, although a causal role of volume overload has not been established, factors beyond volume overload are important mediators of intradialytic hypertension in many patients [22].
The most common causes of RV volume overload are tricuspid and/or pulmonary regurgitation in the presence of various cardiac pathologies.
As mentioned above, redistribution of pulmonary capillary perfusion takes place in patients with cardiac failure due to pulmonary venous hypertension and volume overload. Changes of lung volumes and mechanics also occur.
IVC collapsibility is predictive of volume responsiveness [29, 42, 71, 72] or intravascular volume overload [73, 74].
Despite the significant advances in HF therapy, many patients are discharged with signs and symptoms of volume overload [6].
In the absence of uremic symptom or volume overload, PD was, nevertheless, initiated due to high level of nitrogen catabolites.
In patients with ESRD, because of the renal anemia, systemic hypertension, volume overload, and the presence of an AVF with high-flow rates, LV systolic and diastolic diameters, wall thickness and cardiac output are increased and indirectly EF is decreased.
For example, diuretics that reduce volume overload in people with heart failure can also cause loss of important nutrients such as potassium, magnesium, calcium, and B vitamins--critical for healthy heart chemistry.
For instance, a patient with jugular venous distension and diffuse rules may be described as having "dyspnea" or "volume overload" as diagnoses, rather than the more specific "acute systolic congestive heart failure."
* volume overload: oedema, HT, heart failure, pulmonary oedema
Colloids, such as albumin, blood, plasma, and Dextran 40, are useful for patients with fluid volume overload because they expand the intravascular spaces without adding significantly more fluid.
The goal of fluid replacement therapy is to maintain adequate cardiac output and perfusion of organs, without creating volume overload that causes tissue oedema (decreasing delivery of oxygen and nutrients to the organs) and places extra workload on the heart.
