Oxygen partial pressure (paO2) and saturation (saO2) are 2 different things - read about the difference. Saturation can be measure directly/invasively (saO2) or indirectly/peripherally (spO2).

Jul 10, 2008 · PaO2 stands for the partial pressure of O2 in arterial blood, measured in mmHg. SaO2 is the arterial O2 saturation.

Oct 22, 2014 · The physiology of SaO2 and SpO2 is totally different. SaO2 is directly related Hgb and how saturated the blood is with O2 molecules. SpO2 is the measurement of dissolved O2 molecules …

PaO2 and SaO2 are both measures of oxygen content in the blood. However, PaO2 and SaO2 differ slightly in how they measure the oxygen content in the... See full answer below.

May 24, 2024 · Arterial values should be between 85 and 100 mmHg, Venous values should be between 30 and 40 mmHg. A PaO2 is the level of oxygen in your arterial blood.

My instructor's lecture notes state that SpO2 refers to pulse oximetry, and that SaO2 refers to "peripheral capillary saturation". It also says that PaO2 is an invasive procedure used to determine …

Jan 12, 2015 · Hi There, is there anyone who would be kind enough to express what a pre and post ductal oxygen saturation is and how to record these. Where do you place the sa...
