  2. Delta ratio - Wikipedia

    en.wikipedia.org/wiki/Delta_Ratio

    Result 3: if there is a pure HAGMA, the bicarb would be expected to fall at a similar rate as the anion gap rises, since one molecule of acid combines with one molecule of bicarb buffer. So the equation above should be balanced as the change in the AG away from normal (12) is similar to the change in bicarb away from normal (24).

  3. Anion gap - Wikipedia

    en.wikipedia.org/wiki/Anion_gap

    Anion gap can be classified as either high, normal or, in rare cases, low. Laboratory errors need to be ruled out whenever anion gap calculations lead to results that do not fit the clinical picture. Methods used to determine the concentrations of some of the ions used to calculate the anion gap may be susceptible to very specific errors.

  4. High anion gap metabolic acidosis - Wikipedia

    en.wikipedia.org/wiki/High_anion_gap_metabolic...

    An anion gap is usually considered to be high if it is over 12 mEq/L. High anion gap metabolic acidosis is typically caused by acid produced by the body. More rarely, it may be caused by ingesting methanol or overdosing on aspirin. [1] [2] The delta ratio is a formula that can be

  5. Metabolic acidosis - Wikipedia

    en.wikipedia.org/wiki/Metabolic_acidosis

    The anion gap is calculated by subtracting the sum of the serum concentrations of major anions, chloride and bicarbonate, from the serum concentration of the major cation, sodium. (The serum potassium concentration may be added to the calculation, but this merely changes the normal reference range for what is considered a normal anion gap)

  6. Renal compensation - Wikipedia

    en.wikipedia.org/wiki/Renal_compensation

    In respiratory acidosis, the kidney produces and excretes ammonium (NH 4 +) and monophosphate, generating bicarbonate in the process while clearing acid. There is also an excretion of Cl- and a reabsorption of sodium, resulting in a negative urinary anion gap. [5] In respiratory alkalosis, less bicarbonate (HCO 3 −) is reabsorbed, thus ...

  7. Urine anion gap - Wikipedia

    en.wikipedia.org/wiki/Urine_anion_gap

    Urine NH 4 + is difficult to measure directly, but its excretion is usually accompanied by the anion chloride. A negative urine anion gap can be used as evidence of increased NH 4 + excretion. In a metabolic acidosis without a serum anion gap: A positive urine anion gap suggests a low urinary NH 4 + (e.g. renal tubular acidosis).

  8. Hyperchloremic acidosis - Wikipedia

    en.wikipedia.org/wiki/Hyperchloremic_acidosis

    Hyperchloremic acidosis is a form of metabolic acidosis associated with a normal anion gap, a decrease in plasma bicarbonate concentration, and an increase in plasma chloride concentration [1] (see anion gap for a fuller explanation).

  9. Winters's formula - Wikipedia

    en.wikipedia.org/wiki/Winters's_formula

    It is slower than the initial bicarbonate buffer system in the blood, but faster than renal compensation. Respiratory compensation usually begins within minutes to hours, but alone will not completely return arterial pH to a normal value (7.4). Winter's Formula quantifies the amount of respiratory compensation during metabolic acidosis. [8]
