This process is experimental and the keywords may be updated as the learning algorithm improves. 2021-02-23 · Capillary filtration coefficient, vascular resistance, and compliance in isolated mouse lungs filtration coefficient: a measure of a membrane's permeability to water; specifically, the volume of fluid filtered in unit time through a unit area of membrane per unit pressure difference, taking into account both hydraulic and osmotic pressures. Capillary hydrostatic pressure = 25 mm Hg Venous hydrostatic pressure = 5 mm Hg Arterial pressure = 80 mm Hg Interstitial fluid hydrostatic pressure = −5 mm Hg Interstitial colloid osmotic pressure = 10 mm Hg Capillary filtration coefficient = 10 ml/min/mm Hg What is the rate of net fluid movement across the capillary wall?

2020-07-10 · However, further investigation shows that in most capillary beds, there is a net filtration that continues throughout the capillary length, and many Starling relationships are invalid. Traditionally, the reflection coefficient of proteins across the capillary wall is assumed to be approximately one.

Using an isolated, Ringer-perfused lung preparation, we measured values of the filtration coefficient and reflection coefficients of NaCl, mannitol, sucrose, raffinose, inulin, and albumin for the pulmonary capillary endothelium of adult rabbits. We found a filtration coefficient value of 1.00 × 10-3 cm 3 sec-1 cm H 2 O-1.

/ Bentzer, Peter; Kongstad, Lis; Grände, Per-Olof. In: American Journal of Physiology: Heart and Circulatory Physiology, Vol. 280, No. 6, 2001, p.H2697-H2706. Research output: Contribution to journal › Article Measuring the capillary filtration coefficient (CFC) from the transvascular fluid filtration following a fixed increase in transcapillary hydrostatic pressure is a common method to estimate capillary hydraulic permeability (conductivity) in an organ. Capillary filtration coefficient (CFC), vascular resistance (R), and perfusate O2 content were measured in each period. The arterial O2 content fell from fully equilibrated to 0.25 vol% during the use of N2. R fell from about 6 mmHg X min X 100 g X ml-1 during O2 bubbling to approximately 1.0 with N2. 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 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.

v=Kf[(Pe-Pt)-d(nc-nt)], (1) Capillary filtration coefficients (KI,~) were determined in the isovolumetric loop by suddenly increasing venous pressure and observing the volume changes of intes- tine. The volume change after venous pressure elevation is characterized by two distinct components: an initial rapid Capillary filtration coefficient of the calf capillary bed, measured by computer‐based multistep strain gauge plethysmography, increased significantly after 23.5 h at altitude when symptoms were most severe: 4.45 (2.76–6.03) to 6.31 (3.86–11.07) ml min –1 per 100 g of tissue mmHg –1, median (range) (P <0.02).
