Advocates of the pH-stat method argue that since hemoglobin's affinity for oxygen increases as temperature decreases the addition of CO2 or decrease in ventilation (resulting in a respiratory acidosis) during this method will counter the left shift and therefore oxygen release at the tissues will be improved.
