What pH indicates metabolic alkalosis?

Metabolic alkalosis is a condition characterized by an elevated pH in the blood, resulting from a decrease in hydrogen ions or an increase in bicarbonate. A pH of 7.45 or higher is indicative of alkalosis. In the context of blood pH levels, the normal range is typically defined as 7.35 to 7.45, so any value above 7.45 suggests an alkaline state, specifically pointing towards metabolic alkalosis when associated with appropriate clinical symptoms and laboratory findings.

In contrast, a pH value of 7.25 or lower would suggest acidosis, which is the opposite condition. A pH value between 7.35 and 7.45 represents the normal physiological range, indicating a healthy acid-base balance. Lastly, a pH of 7.50 or higher, while also indicating alkalosis, may point towards a more severe or acute case; however, the threshold for diagnosing metabolic alkalosis is specifically at 7.45. Therefore, recognizing that a pH of 7.45 or higher aligns with the criteria for metabolic alkalosis is essential for accurate diagnosis and treatment.
