Background

Clinical Features

  • Hyperventilation

Differential Diagnosis

Evaluation

  • alkalemia = pH >7.42
  • respiratory alkalosis = pCO2 <38
  • May lead to Hypocalcemia, Hypokalemia
  • Check for a concurrent acid/base disturbance
    • always check for an AG
    • for every 10mm pCO2 <40, HCO3 expected to decrease by 1-3.5 mEq
    • if HCO3 < 24 - (40-pCO2)/10 x 2.5 (+/-1) then there is a superimposed primary metabolic acidosis
    • if HCO3 > 24 - (40-pCO2)/10 x 2.5 (+/-1) then there is a primary metabolic alkalosis, or acute respiratory alkalosis without time for metabolic compensation
