WebThe alpha-stat strategy of ectotherms maintains the temperature-uncorrected arterial PCO2 and pH at normothermic values (i.e., 40 mmHg and 7.4, respectively), irrespective of the body temperature. In contrast, the pH-stat of hibernators maintains the temperature-corrected pH and PCO2 at the normal values at the different body temperatures. WebJun 10, 2015 · The alpha-stat hypothesis suggests we always interpret our blood gases as corrected to the same temperature (normal body temperature) irrespective of what the body temperature actually is. The pH-stat hypothesis instead recommends that we always correct the temperature to the core body temperature. Each approach has its merits and … how apple helps in weight loss
