SaO2 and SpO2 readings differ because pulse oximetry measures the oxygen saturation of only func-tional hemoglobin. SaO2 readings indicate the saturation of both functional and non-functional …

SaO2 is determined by the PO2 to which the blood is exposed in the lungs (in this case 160 mm Hg) and the position of the oxygen dissociation curve. With a normally-positioned curve, the SaO2 at this …

SaO2 is the percentage of available binding sites on hemoglobin that are bound with oxygen in arterial blood. The O2 dissociation curve (and hence the SaO2 for a given PaO2) is affected by PaCO2, …

The blood oxygen level measured with an oximeter is called your oxygen saturation level (abbreviated O2sat or SaO2). This is a percentage of how much oxygen your blood is carrying compared to the …

The paper describes how pigmented skin can cause an over-estimate of SaO2 in individuals with an SaO2 of below 80%. Feiner et al (2007) also describes discrepancies based on gender.

PaO2/FiO2 < 300 is two SOFA points and will support Severe Sepsis. Acute Hypoxic Respiratory Failure. All materials contained in this document are protected and the property of Brundage Medical …

Oct 10, 2024 · Because the calibration curve was developed using healthy volunteers, measured SpO2 can differ from SaO2 significantly at low values (e.g. an SpO2 less than 75%).
