The method was validated in terms of consistency of values obtained on the same individual at various times, the correspondence between values obtained on a group of normal persons, and the agreement between values reported here and those of earlier workers The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity) This is called the whole body capillary filtration coefficient. The filtration coefficient can also be expressed for separate parts of the body in terms of rate of filtration per minute per millimeter of mercury per 100 grams of tissue. On this basis, the filtration coefficient of the average tissue is about 0.01 ml/min/mm Hg/100 g of tissue. (2001) Bentzer et al. American Journal of Physiology - Heart and Circulatory Physiology.

As the blood moves along the length of the capillary, the rate of fluid filtration declines. 1997-04-01 · The capillary filtration coefficient (Kf,c) or hydraulic conductance "measures the total capacity of the entire microvascular system to filter fluid when the microvascular pressure is increased" (Taylor et al., 1997). The Kf,c is the product of the surface area and the hydraulic conductivity per square centimeter. 1) About the glomerular filtration barrier and its relationship to the filtration coefficient.2) How the filtrati In this lesson, you'll learn the following.

1977-07-01 · We found the capillary filtration coefficient value to be 8.3 × 10 −5 cm 3 sec −1 cm H 2 O −1, which, when normalized for the estimated exchange area, is at least a factor of 2 larger than the value found for adult

Capillary filtration coefficient: the technique and its application to the small intestine.

Kfc is a product of hydraulic conductivity (Lp) and filtration surface area (SA) that evaluates convective This is called the whole body capillary filtration coefficient. The filtration coefficient can also be expressed for separate parts of the body in terms of rate of filtration per minute per millimeter of mercury per 100 grams of tissue. On this basis, the filtration coefficient of the average tissue is about 0.01 ml/min/mm Hg/100 g of tissue.

Net movement of fluids across a capillary Expressed by the Starling equation.

The capillary filtration coefficient, a sensitive measurement of hydraulic conductivity, was unchanged over 2 h (0.33 +/- 0.03 ml. min(-1). cmH(2)O(-1). 100 g(-1)) in a control group ventilated with low peak inflation pressures (PIP) but increased 4. 3-fold after high PIP injury.

The filtration coefficient consists of two components as the net fluid flux is dependent on: the area of the capillary walls where the transfer occurs the permeability of the capillary wall to water. 1977-07-01 · We found the capillary filtration coefficient value to be 8.3 × 10 −5 cm 3 sec −1 cm H 2 O −1, which, when normalized for the estimated exchange area, is at least a factor of 2 larger than the value found for adult The capillary filtration coefficient (CFC) is assumed to reflect both microvascular hydraulic conductivity and the number of perfused capillaries at a given moment (precapillary sphincter activity). Estimation of hydraulic conductivity in vivo with the CFC method has therefore been performed under conditions of unchanged vascular tone and metabolic The capillary filtration coefficient was measured in human extremities by a simplified technique using the capacitance plethysmograph. The method was validated in terms of consistency of values obtained on the same individual at various times, the correspondence between values obtained on a group of normal persons, and the agreement between values reported here and those of earlier workers the coefficient of capillary filtration can be expressed in ml'min,/mmHg/100ml. Subjects Studied Measurements of the coefficient of capillary filtration were obtained from 19 healthy control subjects, 15 patients with definite or classical rheumatoid arthritis (Ropes, Bennett, Cobb, Jacox, and Jesser, 1959) and no history of oedema, The slope of this line—the capillary filtration coefficient—agreed with previously reported values. In each case the separate filtration rates were used to construct a curve from which to calculate the capillary filtration coefficient for that condition.
