You are studying the behavior of a perfluorocarbon-based O2 carrier as an emergency treatment for hypoxemia. It has an approximate molecular radius of 1.7 nm. Consider ultrafiltration through the kidney (glomerular membrane pore radius 4 nm, length 610 nm). Assuming a therapeutic dose in the blood of 19 mM and 2 mMin the filtrate, determine. A. The reflection coefficient of the molecule. B. The concentration immediately inside the pore.
C. The effective osmotic pressure across the membrane.
