Respiratory compensation is one of three major processes the body uses to react to derangements in acid-base status (above or below pH 7.4). 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 ...
Hyperventilation due to the compensation for metabolic acidosis persists for 24 to 48 hours after correction of the acidosis, and can lead to respiratory alkalosis. [3] This compensation process can occur within minutes. [4] In metabolic alkalosis, chemoreceptors sense a deranged acid-base balance with a plasma pH of greater than normal (>7.4 ...
Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO 2 of 40 mmHg (5.3 kPa). [2] A base deficit (i.e., a negative base excess) can be correspondingly defined by the amount of strong base that must be added.
Recall that the relationship represented in a Davenport diagram is a relationship between three variables: P CO 2, bicarbonate concentration and pH.Thus, Fig. 7 can be thought of as a topographical map—that is, a two-dimensional representation of a three-dimensional surface—where each isopleth indicates a different partial pressure or “altitude.”
The second step is renal compensation that occurs over 3–5 days. With renal compensation, renal excretion of carbonic acid is increased and bicarbonate reabsorption is increased. For instance, PEPCK is upregulated in renal proximal tubule brush border cells, in order to secrete more NH 3 and thus to produce more HCO 3 −. [1]

Results 2 and 4 are the ones which have mixed acid–base disorders. Results 1. and 4. are oddities, mathematically speaking: [citation needed] Result 1: if there is a normal anion gap acidosis, the (AG – 12) part of the equation will be close to zero, the delta ratio will be close to zero and there is no mixed acid–base disorder. Your ...
[1] [4] This condition is one of the four primary disturbances of acid–base homeostasis. [5] Respiratory compensation is also a condition where increased respiration reduces carbon dioxide sometimes to level below the normal range. In this case it is a physiological response to low pH from metabolic processes and not the primary disorder.
