Abstract:
We report a case of triple acid-base disorder with metabolic alkalosis as the primary disorder in a 65-year-old man due to ingestion and application to leg ulcers of baking soda (calcium bicarbonate). The blood pH was 7.65 with hypochloremia, hypokalemia, and prerenal azotemia. He was treated with isotonic saline with K replacement, and the patient improved without any adverse clinical consequences. We discuss the causes, mechanisms, and management of Cl-responsive (depletion) metabolic alkalosis.

Diagnosing Acidosis and Alkalosis
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and HCO3− values are examined to...

Respiratory Acidosis and Alkalosis
Respiratory acidosis occurs due to an increase in the partial pressure of carbon dioxide PCO2 in the blood. It often arises from shallow breathing or impaired gas exchange caused by...
