Base excess on blood gas
Blood Gases | Cornell University College of Veterinary Medicine
B.E/B.D. the Base Excess or Base Deficit - reflects the change in all blood buffering systems. It is the most reliable indicator of the metabolic component of an acid-base disturbance. The normal value range in Calgary is -5 to +1. If the B.E. is > +1 = Alkalemia. If the B.E. is < -5 = Acidemia

(10) The purpose of the specialty of blood gas analysis is to evaluate pulmonary function by measuring pCO2, pO2, pH, and hemoglobin in arterial blood by automated techniques. Instrument calculated values such as base excess, P50, oxygen content, oxygen saturation and associated parameters are also encompassed in this specialty.

On a blood gas analyser, available chemical buffers (including bicarbonate) are expressed as the BE (Base Excess) number and the normal range is between –2 and +2mmol/L As the body becomes more acid, buffer chemicals bind to H+ ions and the number of available buffers drops, so the BE figure falls.

When to evaluate / re-check a blood gas depends on how abnormal the values are (50). If very abnormal OR a significant change has been made (e.g. Surfactant, HFOV has been commenced for example), the blood gas may need re-checking within 30 minutes. If the neonate is stable, then it …

Base Excess . This often confusing number on the ABG tells us how much alkaline (base) one would have to add in mmol/L to get to a neutral pH of 7.4. In other words a base excess of ‘MINUS 6′ means we would have to ADD 6mmol of bicarbonate to get to a pH of 7.4.

Base Excess of ECF . Effects of Acid-Base Balance on Oxygen Back to Main Manual Index Acids and pH The pH is a method of expressing extremely small concentrations of acid in solution. The scale is exponential — a change of one unit is actually a ten-fold change. A solution with pH of 1 has ten times as much acid as a solution with pH of 2.

Base Excess = Observed BB - Normal BB. If the observed BB is less than the normal BB, the BE is a negative value and is called a base deficit. This means that acid has been added to the blood or base removed. If the observed BB is greater than the normal BB, the BE is a positive value and is called a base excess.

Dec 04, 2007 · Analyzing a blood gas, even in the face of a complicated acid-base disorder, is well within the scope of even a beginning student. There is so much written about blood gases and acid-base disorders, however, and from so many perspectives, that it might look like a hopeless task.
