uestions The presence of dyshemoglobins will cause a calculated % SO2 result to be falsely (elevated, decreased) and a pulse oximeter %SpO, result to be falsely (elevated, 6. When arterial blood from a normal patient is exposed to room air a. pCO, increases; pO2 decreases b. pCO, decreases: pO, increases c. pCO2 decreases; pO, decreases d. pCO, increases pO, increases a. Elevated, elevated b. Decreased, decreased c. Elevated, decreased d. Decreased, elevated 7. A patient's arterial blood gas results are as follows: pH 7.37;pCO,75 mm Hg; HCO,,37 mmol/L.
