Webwill alter the pH. As a general rule, a low pH with a high PaCO 2 suggests a respiratory acidosis, while a low pH with a low PaCO 2 suggests a metabolic acidosis. Box 1 Reference ranges for arterial blood gases pH 7.35 – 7.45 PaO 2 80 – 100* mmHg 10.6 – 13.3 kPa PaCO 2 35 – 45 mmHg 4.7 – 6.0 kPa HCO 3ˉ 22 – 26 mmol/L WebSep 22, 2024 · An O2 sat of 90% corresponds to a PaO2 of 60 mmHg. This is the minimum oxygen concentration providing enough oxygen to prevent ischemia in tissues. Once the O2 sat falls below 90%, the PaO2 drops quickly into the dangerously hypoxic range as fewer and fewer oxygen molecules are bound to Hgb. We want to try to keep O2 saturation above 90%.
