Dianne Beatty was taken to the hospital in a coma. Calculate the pH of Dianne Beatty s blood based on the above blood gas analysis. Extra bicarbonate was being excreted into the urine. Proteins are particularly important buffers in interstitial fluid. TCO 2 measurements serve as a good indicator for blood HCO 3 - .
Vomiting can result in metabolic acidosis.
The amino acid histidine could be used to prepare a buffer that would be effective at pH 6.5 because the imidazole group in the sidechain has a pKa of 6.0. Calculate the moles of each ionic species of histidine that would be required to prepare a 0.05 M histidine buffer at pH 6.5. Metabolic alkalosis 18. You must think about the lab values that are stated and determine a mechanism that would have caused the compensatory change. This occurs as a result of increased reabsorption of HCO 3 - from the kidney tubules back into the blood.
