A 67-year-old man, a heavy smoker goes to the hospital to investigate the origin of his chest pain. The lab parameters and blood gas values are: Na+: 138 mmol/L, K+: 4.8 mmol/L, glucose: 5.2 mmol/L, creatinine: 98 mmol/L, pCO2: 55 mmHg, pH: 7.32, actual HCO3-: 40 mmHg, BE: 4.2 mmol/L. What kind of acid-base disorder do you suppose? What could be the cause of the disorder?
Our physiology lab manual posed this and some related questions to prepare us for our acid-base balance experiment. The topic itself has been dense to study and wrap my brain around, so it was nice to see the knowledge applied in this direct, clinical way.
My diagnosis: compensated respiratory acidosis due to COPD.
