Ph-stat法是什么
WebDec 31, 2024 · The pH-stat aim to maintain a pH of 7.4 at the lower temperatures of hypothermic cardiac bypass is achieved by having a pCO 2 level which is higher than that required for alpha-stat management. This means that from the alphastat point of view, pH-stat management results in a respiratory acidosis at the lower temperature. ... WebFeb 4, 2003 · Up to now, the main application of the pH-stat titration has been for nitrification monitoring. In this article, we present a theoretical model of pH-stat titration, which predicts the response to any reaction involving the production or consumption of protons, hydroxyl ions, or inorganic carbon chemical species (CO 2, HCO 3 −, CO 3 =). This ...
