A 50 year old man came to the ED after returning from foreign travel. His symptoms included persistent diarrhea (over the past 3 days) and rapid respiration (tachypnea). Blood gases were drawn with the following results: pH = 7.21 pCO2 = 19 mm Hg pO2 = 96 mm Hg HCO3- = 7 mmol/L SO2 = 96% calculated (reference range, >95%) 1. What is the patient's acid-base status? 2. Why is the HCO3- level so low? 3. Why does the patient have rapid respiration?
