  2. Ultrasonography of chronic venous insufficiency of the legs

    (Hemodynamics is the study of blood flow and of the laws that govern the circulation of blood in the blood vessels.) [5] It follows that the examiner's knowledge of venous hemodynamics is crucial, which can be a real barrier to a radiologist, untrained in this field, who might wish to carry out these examinations.

    For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall. In most cases, the mean velocity is used. [18] There are many ways to measure blood flow velocity, like videocapillary microscoping with frame-to-frame analysis, or laser Doppler anemometry. [19]

    Since blood flow is important for wound healing, TCOM is often used to gauge the ability of tissue to effectively heal. [1] To perform the test, one set of electrodes are placed on viable tissue (e.g. the chest) as a control and a second set is placed around the tissue in question (e.g. legs or feet). The electrodes may mildly heat the skin to ...

  5. Laser Doppler velocimetry - Wikipedia

    en.wikipedia.org/wiki/Laser_Doppler_velocimetry

    Laser Doppler velocimetry is used in hemodynamics research as a technique to partially quantify blood flow in human tissues such as skin or the eye fundus. Within the clinical environment, the technology is often referred to as laser Doppler flowmetry; when images are made, it is referred to as laser Doppler imaging .

  6. Lumped parameter model for the cardiovascular system

    en.wikipedia.org/wiki/Lumped_parameter_model_for...

    The lumped parameter model consists in a system of ordinary differential equations that adhere to the principles of conservation of mass and momentum balance. The model is obtained exploiting the electrical analogy where the current represents the blood flow, the voltage represents the pressure difference, the electric resistance plays the role of the vascular resistance (determined by the ...

  7. Laser Doppler imaging - Wikipedia

    en.wikipedia.org/wiki/Laser_Doppler_imaging

    The rate of mean blood flow depends on both blood pressure and the hemodynamic resistance to flow presented by the blood vessels. LDI can enable mapping of the local arterial resistivity index, and the possibility to perform unambiguous identification of retinal arteries and veins on the basis of their systole-diastole variations, and reveal ...

    [2] [3] Nevertheless, CVP monitoring is a useful tool to guide hemodynamic therapy. The cardiopulmonary baroreflex responds to an increase in CVP by decreasing systemic vascular resistance while increasing heart rate and ventricular contractility in dogs. [4] Trend of central venous pressure as a consequence of variations in cardiac output.

  9. Venous stasis - Wikipedia

    en.wikipedia.org/wiki/Venous_stasis

    Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound
