3. Normal values and an example of critical or alert value ranges for arterial blood gas analysis: Normal (7) Critical (7) pH 7.35 to 7.45 ≤7.20 or ≥7.60 Pa CO 2 35–45 mm Hg ≤ 20 or ≥70 mm Hg* Pa O 2 83–108 mm Hg** ≤40 mm Hg *Only in cases with a marked decrease in pH **Breathing room air at sea level; declines with age

4. All documentation of completion of maintenance, quality control, and specimen results is maintained for a minimum of two years or as otherwise required by regulatory agencies (3).
