Answer

Electrolyte analysis is unnecessary, although several abnormalities may be present in the setting of hyperventilation. Serum phosphorus and ionized calcium may be diminished in patients with hyperventilation and carpopedal spasm, Chvostek sign, or Trousseau sign. The serum calcium level may be within the reference range.
