Therefore the base deficit or the Negative base excess of the original sample is 18 mmol/Litre. ‘Base Excess’ quantifies the metabolic contribution to the acid-base disorder. Normal value is ‘O’. CONCEPT OF pH: The term pH (p stands for Potenz or Power) was introduced by Sorensen to express the molar H+ ion concentrations.

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. Practically speaking the base excess (or base deficit) tells us whether there is a metabolic problem (regardless of the CO2 level that determines respiratory acidosis and alkalosis) The Henderson-Hasselbalch Equation

base excess is positive. treatment with NaHCO3 restores pH to normal. there is more renal excretion of H+ ions. Compensatory mechanisms in metabolic acidosis includes: a fall in pH. decreased CO2 formation. decreased minute volume. an alkaline urine. reduction in the PCO2 of alveolar gas. With respect to blood pressure control:

• The amount of base added is stoichiometrically equivalent to the amount of acid originally present. • The cation of a strong base and the anion of a strong acid do not undergo hydrolysis. • Therefore, pH = 7.00. 4. After the equivalence point. • The pH is determined by the excess base …

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.

The causes of encephalitis can be defined as those due to direct infection of the central nervous system (CNS), para-, or post-infectious causes, and non-infectious causes. Infectious causes include numerous viruses, bacteria (especially intracellular bacteria such as Mycoplasma pneumoniae), parasites and fungi.

(BB- is also called Base Excess (BE), understanding that a negative value indicates a base deficit. Base excess reflects addition or removal of hydrogen ions except when adding or removing CO2. Added H+ is bound by the buffer anions, and base excess falls in direct proportion to the added H+.
