In general, the cause of a hyperchloremic metabolic acidosis is a loss of base, either a gastrointestinal loss or a renal loss [citation needed]. Gastrointestinal loss of bicarbonate (HCO − 3) [citation needed] Severe diarrhea (vomiting will tend to cause hypochloraemic alkalosis) Pancreatic fistula with loss of bicarbonate rich pancreatic fluid
Acid–base imbalance is an abnormality of the human body's normal balance of acids and bases that causes the plasma pH to deviate out of the normal range (7.35 to 7.45). In the fetus, the normal range differs based on which umbilical vessel is sampled (umbilical vein pH is normally 7.25 to 7.45; umbilical artery pH is normally 7.18 to 7.38). [1]
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.”

One difficulty in evaluation acid-base derangements is the presence of multiple pathologies. A patient may present with a metabolic acidosis process alone, but they may also have a concomitant respiratory acidosis. Winters's formula gives an expected value for the patient's P CO 2; the patient's actual (measured) P CO 2 is then compared to this ...
[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.

The respiratory brainstem centers can only compensate for metabolic acid-base disturbances (metabolic acidosis and metabolic alkalosis). Renal compensation is needed to balance respiratory acid-base syndromes (respiratory acidosis and respiratory alkalosis). The kidneys can compensate for both, respiratory and metabolic acid-base imbalances.
