The principals of this new paradigm are

A low pH of the blood or body fluid is an Acidemia
A high pH of the blood or body fluid is an Alkalemia
An acidosis is a process producing a lower pH or in the direction of an acidemia.
An alkalosis is a process producing a higher pH or in the direction of an alkalemia.

These changes is terminology have profound implications for the concepts of acid base terminology. For instance a metabolic acidosis means that there is or has been a process producing metabolic acids. This does not mean that the pH is abnormally low. That is acidemia which is different from acidosis.

The severity of a metabolic acidosis is based on the HCO3- level and not the pH.
The severity of a respiratory acidosis, is based on the arterial PaCO2- and not the pH
