Part Descriptions

LP15428-3   Base deficit
In human physiology, base deficit refers to a decrease in the total serum concentration of bicarbonate. It can be indicative of metabolic acidosis (acidosis describes the abnormal conditions that results from an excess of acid within the blood such as in a case of lactic acidosis due to anaerobic metabolism) or compensatory respiratory alkalosis (alkalosis describes a conditions that results from an excess alkali (base) within the blood). A base deficit indicates an excess of acid. It refers to the amount of base needed to titrate a serum pH back to normal (healthy human-arterial blood pH varies between 7.35 and 7.45) when the contribution of respiratory factors is taken out of the equation.
Base deficit is usually reported as a negative base excess. Therefore a base excess of -5 is a base deficit of 5. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See http://creativecommons.org/licenses/by-sa/3.0/ for details. Source: Wikipedia, Base deficit

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
