The elevated pH indicates alkalosis.The bicarbonate level is normal,and so is the oxygen partial pressure.Loss of carbon dioxide is the cause of the alkalosis,which would occur in response to hyperventilation.Diarrhea and vomiting would cause metabolic alterations,COPD would lead to respiratory acidosis,and the person with emphysema most likely would have combined metabolic acidosis on top of a mild,chronic respiratory acidosis.
