• Compensatory Response to Respiratory Alkalosis
  • Acute response - lowers HCO3 by 2 meq/L for every 10 mmHg decline in PCO2
  • Chronic response (reduced PCO2 persistent for more than 3-5 days) - HCO3 level falls by 4 to 5 meq/L for every 10 mmHg reduction in PCO2

• Major consequence of alkalosis - hypokalemia
  Consider higher level of care and possible intubation for management at pH>7.55

• Acetazolamide
  • inhibits the activity of carbonic anhydrase
  • produces both NaCl and NaHCO3 loss in the urine
  • used as a diuretic in patient with volume overload and metabolic alkalosis
