Standard Bicarbonate (SB)

The standard bicarbonate is the plasma bicarbonate concentration measured at 37 ° C for whole blood at a partial pressure of carbon dioxide at 5.32 kPa (40 mm Hg) and hemoglobin at 100% oxygen saturation. It is not affected by respiration and is therefore a good indicator of metabolic changes. Arterial blood was drawn and measured with a blood gas analyzer. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Reduced in metabolic acidosis, such as uremia, diabetic ketoacidosis, severe diarrhea. Normal value: Children: 21-25mol/L Adult: 22-28mol/L Above normal: Above normal, it is easy to cause metabolic alkalosis. negative: Positive: Tips: Some drugs can affect the pH of the blood. The doctor should inform the doctor about the recent medication before the test. Normal value Children 21 to 25 mmol / liter. Adults 22 to 28 millimoles per liter. Clinical significance Increased in metabolic alkalosis, such as adrenal hyperfunction, lack of potassium and so on. Reduced in metabolic acidosis, such as uremia, diabetic ketoacidosis, severe diarrhea. Low results may be diseases: high uremia results may be diseases: pediatric acute respiratory failure, pulmonary encephalopathy, acute respiratory failure precautions 1. Conventional arterial blood should be taken for examination. If venous blood is to be taken, the forearm should be immersed in warm water at 45 °C for 20 minutes to make the venous blood arterial. It is not advisable to use a tourniquet when drawing blood. 2. Flush with heparin beforehand in the syringe. 3. Ensure that the needle and needle of the syringe are tightly combined, and there must be no air leakage to ensure that the blood sample does not come into contact with the outside air. 4. Send the specimen in time. Inspection process Same electrode assay. Not suitable for the crowd No taboos. Adverse reactions and risks 1. Infection: Pay attention to aseptic operation when collecting blood, avoid contamination of water and other parts at the blood collection site to avoid local infection. 2, bleeding: after the blood is given a full compression time, especially coagulopathy, bleeding tendency, to avoid local subcutaneous oozing, bruising and swelling.
