Strong ion theory

WebOur understanding of acid-base balance was revolutionized in 1983 by Stewart’s development of strong ion theory . The strong ion approach has two novel aspects: acid-base balance is examined using a systems approach, and a clear conceptual distinction is made between dependent and independent variables. Independent variables influence a ... WebPeter Arthur Robert Stewart (1921–1993) was a Canadian physiologist who introduced an alternate approach to understanding acid–base physiology . He outlined his model in a paper in 1978, [1] and explained it his 1981 book, How to Understand Acid–Base. [2] The book was unavailable for many years, then made available on-line and finally ...
