actual bicarbonate

The actual bicarbonate (AB) refers to the actual content of HCO3 measured by blood separation of plasma under conditions of air isolation. AB is the actual plasma HCO3- content, SB is the temperature of 37 ° C, PC025.32kPa (40mmHg), SaO2100% measured under the condition of HCO3- content is also excluded from the impact of changes in respiratory factors, so SB can more accurately reflect Metabolic acid-base balance. Basic Information Specialist classification: Respiratory examination classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Avoid taking medicines before checking. Normal value AB is the actual plasma HCO3- content, SB is the temperature of 37 ° C, PC025.32kPa (40mmHg), SaO2100% measured under the condition of HCO3- content is also excluded from the impact of changes in respiratory factors, so SB can more accurately reflect Metabolic acid-base balance. AB children 21 ~ 25mmol / L, adults 22 ~ 28mmol / L. SB children 20 ~ 24mmol / L, adult 21 ~ 25mmol / L (blood gas acid and alkali analyzer). Clinical significance Abnormal result: normal person SB=AB. Patient SB is normal, and AB>SB has respiratory acidosis, AB People who need to be examined: people with unbalanced acid-base metabolism. Precautions Inappropriate population: acid-base metabolic balance, does not belong to this test. Contraindications before inspection: Avoid taking drugs indiscriminately. Requirements for examination: Maintain an easy state and measure arterial blood pressure. Inspection process Blood gas analysis should pay attention to the heparin anticoagulant arterial blood 2ml when collecting the test sample. After the blood is drawn, it is required to be sealed tightly. It can not be exposed to the air, and it can be sent immediately. The heat can be placed in the refrigerator and the patient's body temperature is recorded. Not suitable for the crowd no. Adverse reactions and risks no.
