The suitable power of hydrogen (pH) of the internal environment is essential for the organism’s metabolism. The value of PH is 7.35–7.45 and the mean is 7.40. The process of maintaining a relatively stable internal environment is called the acid-base balance. However the acid-base disorders usually occur in the pathological state, in which the acid or base overloads or is severely inadequate. The judgment of acid-base state based on the arterial blood gas analysis has been the basic method in the clinical diagnosis and treatment.
