A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO 3 – in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis. Some ABG results also show hemoglobin and serum electrolyte values. Bicarbonate (HCO3): A chemical buffer that helps stabilize blood pH. Completed BHMS and MD in Homeopathy in January 2018 and also has a clinical experience of about 6 years. The equation to find the anion gap is (Na + K+) - (cl + [HCO3-]) a high value can be caused by keto or lactic acidosis, or renal failure. pH.

As a … 10-20mmol/L OXYGEN STATUS p50a - oxygen tension at 50% saturation on ODC. Components of the Arterial Blood Gas The arterial blood gas provides the following values: pH Measurement of acidity or alkalinity, based on the hydrogen (H+) ions present. The concentration of oxygen being breathed, called the fraction of breathed in oxygen (FiO2), is also normally reported. The normal values listed here—called a reference range—are just a guide. Respiratory acidosis may be acute or chronic. There is a trend towards the use of venous blood, as venous punctures are less invasive for the patient and less complex for healthcare providers.. Clinical parameters differ between arterial and venous samples. All rights reserved. Values at sea level: Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa) Arterial blood pH: 7.38 to 7.42; Oxygen saturation (SaO2): 94% to 100%; Bicarbonate (HCO3): 22 to 28 milliequivalents per liter (mEq/L) While drawing venous sample make sure that no tourniquet is applied, artery is not compressed and sample is drawn against the flow of blood towards heart. This blood sample is then into the blood-gas analyzing unit. The Arterial Blood Gas (ABG) is a blood test which measures the pH, Carbon dioxide and Oxygen levels of blood. This in turn causes other vital organs like the heart and kidneys to act abnormally. Though issues are unusual, take care with the arm or leg that had the blood draw.
