WebSep 22, 2024 · The Oxygen-Hemoglobin Dissociation Curve shows the percent of oxygen binding to Hgb per mmHg. An O2 sat of 90% corresponds to a PaO2 of 60 mmHg. Note how quickly Hgb loses oxygen below 90% saturation. As the partial pressure of oxygen rises, there are more and more oxygen molecules available to bind with Hgb. WebApr 15, 2024 · An arterial blood gas (ABG) is the traditional method of estimating the systemic carbon dioxide tension and pH, usually for the purpose of assessing ventilation and/or acid-base status. However, the necessary sample of arterial blood can be difficult to obtain due to diminished pulses or patient movement.
