Acidosis is defined by a pH lower than which value?

Acidosis is a condition characterized by an excess of hydrogen ions in the body, leading to a decrease in blood pH. The standard threshold for determining acidosis is a blood pH lower than 7.35. Normal blood pH ranges from about 7.35 to 7.45, and anything below 7.35 indicates acidosis. Therefore, the correct answer reflects the clinical definition of acidosis relating to the pH balance in the body.

A pH below 7.0 is considered highly acidic and would indicate a severe acidosis or even potential systemic failure, while a pH of 7.45 indicates alkalosis, not acidosis. Understanding these values is crucial in assessing and managing patients with acid-base disorders.
