Clinical Significance
The notation of pH expresses the hydrogen ion activity in a solution as the negative logarithm of the hydrogen ion concentration. Hydrogen ion activity reflects the acid-base balance within blood. The lungs, kidneys, and blood work to maintain the acid-base balance with the narrow limits required for normal cell function. pH is clinically significant as a means of determining acid-base disorders that can be caused by several pathologic conditions, such as ventilatory dysfunction and renal or gastrointestinal inadequacy.
