- What is the Glasgow scale and in which cases is it good to use that scale?Hemodialysis is a process by which a machine is used to filter urea and other waste products from an individual’s blood when the kidneys fail. The concentration of urea in the blood is often modeled as exponential decay by the following function: −Kt c(t)=c0e V where K is the mass transfer coefficient (in mL/min), c(t) is the urea concentration in the blood at time t (in mg/mL) and V is the blood volume., and c0 is the initial concentration at time t = 0. Answer the following questions:(a) How long should a patient be put on dialysis to reduce the blood urea concentration from an initial value of 1.65 mg/mL to 0.60 mg/mL, given that K = 340 mL/min and V = 32, 941 mL? b) Derive a general formula for the dialysis time T , in terms of the initial urea concentration c0 and he target urea concentration c (T ) (c) The quantity Kt, is sometimes used as a measure of dialysis treatment adequacy. What are its V units and explain what does this quantity represent?After three minutes, the concentration of drug Zip in the red blood cells is 10 mmoles l-1. What is the average rate of entry of drug Zip into the red blood cells in units of moles min-1 red blood cell-1 during the first three minutes after placing the red blood cells into the bathing solution? Assume that each red blood cell occupies about 1 x 10-13 liters.
