WebOct 22, 2014 · If the ABG is done without a Co-oximeter measurement, you cannot see what else attached to the hemoglobin. A smoker could have an SpO2 of 98% and be complaining of shortness of breath. The PaO2 may also come back low. A co-oximeter might measure the SaO2 at 85% and 10 - 13% COHb. 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%.
