Part Descriptions

LP21258-6   Oxygen saturation
Oxygen saturation (sO2) is defined as the ratio of oxyhemoglobin to "active" hemoglobin (oxyhemoglobin + deoxyhemoglobin). Some say the term oxygen saturation has been erroneously redefined with a denominator of "total" instead of "active" hemoglobin, an ambiguity that can sometimes create confusion when viewing reported values from different instruments (Anesth Analg. 2007 Dec;105(6 Suppl):S5-9.) Oxygen saturation is commonly measured by blood gas analyzers and pulse oximetry. Source: Regenstrief LOINC

LP422982-1   BldCV
Central venous blood is blood found in the interior jugular or subclavian vein sampled via a central venous catheter. The composition of central venous blood is different from mixed venous blood, found in the pulmonary artery and also sampled via catheter, and peripheral venous blood, sampled via venipuncture. Central venous blood contains blood from the upper body, whereas mixed venous blood contains deoxygenated blood from the entire body. Source: LOINC
