WebWhat are the main concepts of pH stat? 1. Maintain constant pH with change in temp. 2. CO2 content has to increase as temperature decreases and has to decrease as temperature increases. 3. Ratio of unprotonated histidine imidazole group to H+ ( alpha value) changes as CO2 content increases. WebIn the 1960s and 1970s, the pH-stat strategy was used widely. In the 1980s, many institutions shifted toward the alpha-stat strategy for pH management mainly because of studies of cold-blooded vertebrates.1 One continuing reason for the popularity of alpha-stat in clinical practice is because no addition of carbon dioxide is required.
