Explain how it is possible for a patient with chronic obstructive pulmonary disease to have a normal extracellular pH while having an elevated partial pressure of carbon dioxide
What will be an ideal response
Elevated partial pressure of carbon dioxide causes respiratory acidosis, which is compensated by an increase in plasma levels of bicarbonate ion. Because the patient cannot breathe off the excess carbon dioxide due to structural changes in the respiratory system, the partial pressure of carbon dioxide stays high, but compensated by bicarbonate.
