What pH level indicates acidosis?

The pH scale measures the acidity or alkalinity of a solution, with a neutral pH at 7.0. A pH level below 7.35 indicates acidosis, which means there is an excess of hydrogen ions in the body leading to increased acidity. This can be due to various conditions, such as respiratory issues that cause carbon dioxide retention or metabolic problems that produce excess acids.

Individuals with a pH level in this range may experience symptoms ranging from fatigue to confusion, depending on the severity of the acidosis. The distinction of a pH below 7.35 is crucial in emergency medicine, as it helps in diagnosing and treating potentially life-threatening conditions.

A pH level above 7.45 indicates alkalosis, which is the opposite condition. Between 7.35 and 7.45 is considered to be a normal range, while a pH of exactly 7.0 reflects a very acidic state but does not necessarily classify as acidosis in the broader context of physiological responses. Therefore, the pH below 7.35 is the definitive measure indicating acidosis.
