97542-5Oxygen content in Central venous bloodActive

Part Descriptions

LP30884-8   Oxygen content
Oxygen content is a component of a blood gas analysis test that helps to evaluate acid-base balance, gas exchange, and voluntary respiratory control. In the blood gas analysis test, blood is drawn from an artery and analyzed in the lab for pH, partial pressure of carbon dioxide, partial pressure of oxygen, bicarbonate content per 100 mL of blood, oxygen saturation, and oxygen content. Oxygen content is the sum of the oxygen that is combined with hemoglobin and the oxygen dissolved in the plasma. The calculation for oxygen content is the following: arterial oxygen content = (Hgb x 1.36)(Oxygen saturation/100)+(partial pressure of oxygen x 0.0031).

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
