Arterial-GASA [GASA] Venous-GASV [GASV] Capillary-GASC [CAB] Mixed Venous-GASMV [GASMV] Minimum Volume 0.2mL (1mL Syringe), 0.8mL (3mL Syringe), 100uL (Capillary tube) Comments A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries. Venous blood gases are often more simple to obtain than arterial gases. The PCO2 of venous blood is usually 4 to 6 mmHg higher and the pH is usually 0.02 to 0.05 units lower than those of arterial blood. blood gas analysis laboratory studies of arterial and venous blood for the purpose of measuring oxygen and carbon dioxide levels and pressure or tension, and hydrogen ion concentration (pH). (See accompanying table.) Analyses of blood gases provide the following information:ƒ Pa O 2 —partial pressure (P) of oxygen (O 2) in the arterial blood (a) Sa O 2 —percentage of available hemoglobin In venous blood sampling, a needle is inserted into a vein to collect a sample of blood for testing. Peripheral veins, typically the antecubital veins, are the usual sites for venous blood sampling.

Xenon-ursköljning/CT: Inert gas inhaleras + CT. Clearance Has the same chloride ion concentration as venous blood. 4.

The location and method of sampling should always be considered when interpreting the results. Assessment of Carbon Dioxide, Bicarbonate and pH In the absence of an arterial line, a venous blood gas sample can be used to evaluate carbon dioxide, pH and bicarbonate. Test Name: VENOUS BLOOD GAS (VBG) General Information Lab Order Codes: VBG Synonyms: Venous blood gas CPT Codes: 82803 - Gases, blood, any combination of pH, pCO2, pO2, CO2, HCO3 (including calculated O2 saturation) Test Includes: VpH (no units), VpCO2 and VpO2 measured in mmHg, VsO2 and VO2AD measured in %, HCO3 and BE measured in mmol/L, both a venous blood gas (VBG) and a serum chemistry panel were needed to obtain these measurements.

Its normal value is 40 mmHg at sea level, while it is 46.5 mmHg in venous blood. Increased values show respiratory acidosis, while decreased values demonstrate respiratory alkalosis. Assessment of oxygenation status. The pO2 on a VBG bears no relationship to the paO2. The VBG is … This blood (venous blood) is relatively lacking in oxygen and relatively rich in carbon dioxide due to the gaseous exchange that has occurred in the capillary bed of tissue cells.
