Blood Flow Volumetric Velocity

Blood Flow Volume is a hemodynamic parameter that describes the speed at which blood flows through a specific vascular junction. Basically, the study of Volumetric Blood Flow is used to assess the blood supply to tissues and organs, as well as to determine pathological conditions such as ischemia, arteriosclerosis, thrombosis, embolism and other diseases of the cardiovascular system.

Based on the basic principles of hemodynamics, the volumetric blood flow rate is defined as the ratio of the amount of blood passing through the measuring area to the duration of observation. This indicator is measured in milliliters per minute (ml/min) and is expressed in the form of a complex of peak current values ​​​​related to the time of measurement. Depending on the volume of the vessel through which blood flows, two approaches can be used: to measure intravascular volume (for example, capillary microcirculation) or the volumetric blood filling of the entire vessel (for example, general metabolic circulation).

Under physiological conditions, under standard air and body temperature conditions, the rate of volumetric circulation depends on the cross-sectional area of ​​the vessel and the flow rate of the flowing blood, which is the product of systolic pressure (cardiovascular pressure). In tissues, as in all intraluminal structures, the speed of blood flow also depends on the formation of tumors, inflammation, and blood flow along with the pulse. Thus, it is not always possible to compare the indicators of BCC or OCS as indicators of the same qualitative characteristics of the hemodynamic state of the body.
