Alkali remaining

Alkali surplus refers to the pH of the blood is acid or alkaline. Under standard conditions, the temperature is 38 ° C, 1 standard atmospheric pressure, PCO 25.32 kPa (40 mmHg), Hb is completely oxygenated, and 1 L blood pH is measured with acid and alkali. The amount of acid or base to be added to 7.40 is BE or BD, which indicates an increase or decrease in alkali storage in whole blood or plasma. Basic Information Specialist classification: Respiratory examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Metabolic acidosis. Normal value: Alkali surplus: -3-3mmol/L Above normal: Metabolic alkalosis. negative: Positive: Tips: Before taboos: Avoid taking drugs. Normal value If acid titration is required, it indicates that the measured blood sample has a high buffer base and is alkali residual. It is expressed by a positive value (ie +BE) and is found in metabolic alkalosis. If titrated with alkali, it indicates that the measured blood sample has a low buffer base, which is a base loss, and is represented by a negative value (ie, -BE), which is found in metabolic acidosis. The reference range is -3 to +3 mmol/L, and the average is 0 mmol/L. Clinical significance Abnormal results: 1. When the pathological increase of BE is positive, the alkali storage in the body is excessive, suggesting metabolic alkalosis. 2, pathological reduction of BE is negative, the lack of alkali storage in the body, suggesting metabolic acidosis. In the case of respiratory acidosis or alkalosis, BE may also have a positive or negative increase due to the compensatory effect of the kidney. People who need to be examined for imbalanced acid-base metabolism. Low results may be diseases: high metabolic acidosis results may be diseases: metabolic alkalosis 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.
