Physiological approach to acid base
Webb1 juli 2024 · The physiological approach quantitates the dominant buffer pair in blood (H 2 CO 3 /HCO 3 −), evaluates the plasma anion gap, measures the secondary responses to … WebbRecent advances in acid–base physiology and in the epidemiology of acid–base disorders have refined our understanding of the basic control mechanisms that determine blood pH in health and disease. These refinements have also brought parity between the newer, quantitative and older, descriptive approaches to acid–base physiology.

Based on the isohydric principle, this system characterizes acids as hydrogen … Webb1 aug. 2007 · Traditionally, clinical acid–base abnormalities have been interpreted using the pH notation proposed by Sorensen, and the P co 2 /bicarbonate model of Henderson and Hasselbalch (H–H). However, for some patients in the operating theatre or intensive care unit (ICU), the traditional method is often inadequate to explain the severity and …
Webbapproach, however. The ÔmodernÕ approach derives from Stewart’s work in physical chemistry. In this review we describe the origins of the traditional approach and discusses related concepts. We then describe Stewart’s approach, including how it is derived and how it may be used to classify acid–base derangements. Webb1 juli 2024 · The traditional approach to acid–base balance is that there are two component defence mechanisms: • physicochemical buffering • acid excretion from the lungs (as CO 2) and the kidneys. In order to understand these mechanisms it is first necessary to understand the principles of buffer systems within the body. …
Webb4 apr. 2002 · Classification of acid–base disorders using Stewart theory. A natural division of acid–base disorders when using Stewart's approach is based on derangements of the independent variable(s). As with the conventional approach, respiratory acidoses or alkaloses are those in which the first independent variable affected is the pCO 2. Webb1 aug. 2024 · Background: Acid-base balance can change as a result of pulmonary oedema and low tissue perfusion in acute heart failure patients. However, its long-term prognostic significance remains to be clarified. Methods: We prospectively examined a cohort of 472 consecutive acute heart failure patients who underwent arterial blood gas analysis on …
