Case Study 1 Jerica Schuebel What appears to be Mary’s problem(s), from the results of her blood work? Mary pH level is slightly acidic because the normal pH is between 7.35 and 7.45. The amount of CO2 that Mary is taking in and dissolving in her blood is also low, because the range is between 38-52 and her CO2 in her blood is 18.1. Her oxygen levels in her blood are high as well because it’s between 70 – 100 and Mary’s levels were 121.0. Lastly the bicarbonate in her blood went down immensely. What sort of change has occurred in her acid-base balance? The acid-base balance is more acidic because it is at 7.31. If there is more than one problem in her blood work results, is there a relationship among those factors? Mary has a low bicarbonate level and a low PCO2 in the blood is metabolic acidosis. Part 2 - Buffers Bicarbonate is one of the main buffers in the blood. Provide a definition of a buffer. A buffer is a solution containing substances which have the ability to minimize changes in pH when an acid or base is added to it”. Give an equation that allows one to calculate the pH of a buffer solution. pH= pK+log[HCO3-]/[H2CO3] Provide the specific form of this equation, including each chemical species, that will allow you to calculate the pH of a bicarbonate buffered solution.
