WebArterial Blood Gas Interpretation. (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2), carbon dioxide (PaCO2), and the pH of an arterial blood sample. Oxygen content (O2CT), oxygen saturation (SaO2), and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by ... 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%. maple grove raceway photos
