perfusion rate

perfusion rate

the rate of blood flow through the capillaries per unit mass of tissue, expressed in milliliters per minute per 100 g.

The perfusion fluid was collected using an EP tube with known weight in the outlet, with the perfusion rate being controlled at 0.
50 and 250 mg/kg/day of Gl-PS treatment significantly increased the mean perfusion rate around the wound in diabetic mice.
The authors conclude that findings are consistent with size-dependent transfer of nanomaterials across human placentas, but they acknowledge that the model involved high-dose exposures over a period of a few hours and that the perfusion rate was representative of placental perfusion late in pregnancy.
Ideally, the lung's transfer rate and the perfusion rate, as described above, should be the same throughout the lung but, in reality, the rates are different in various sections of the lung due to the dynamic conditions of respiration, blood flow, effects of gravity and differences in Dm, Qc, and [theta].
To predict the effectiveness of the treatment and monitor its progress requires in situ measurement of several key parameters, including temperature, blood perfusion rate, radiation dose, oxygen tension (partial pressure of oxygen dissolved in intracellular fluid) and pH - all at the same location within the tumor and at the same time.
The adenosine perfusion rate was individually and dynamically adapted to achieve similar blood flow levels in all pigs at each measurement time point.
A further limitation of the model is that the perfusion rate measured in the explant represents only the late phase of pregnancy, for which the thickness of the barrier layer between the maternal and the fetal circuit is reduced and the number of fetal capillaries is increased (Enders and Blankenship 1999).
The increased marrow fat content would limit exchange between the intravascular and interstitial spaces resulting in a weakened perfusion rate.
Retina is the most metabolically active tissue in the human body [95] and is highly sensitive to the local perfusion rates of the retinal and choroidal circulations.
The study results demonstrated that patients receiving 10 to 15 million cells (n=9) experienced significant improvement in resting perfusion rates at six months as compared to patients receiving 5 million cells (n=6) and control (n=15), as measured by the SPECT total severity score, (-256 versus +13, p=0.
