Which of the following is most likely to increase during hypothermia to 25°C?
Intracellular pH is determined by the pH of neutral water (i.e., when the concentration of the hydroxyl ion equals the concentration of the hydrogen ion). Hypothermia results in an increase in the pH of neutral water with an associated increase in intracellular pH.
The solubility of gases, including oxygen and carbon dioxide, increases under hypothermic conditions. The total content does not change, but the partial pressures decrease.
Hypothermia is associated with a decrease in serum potassium concentration.
Hypothermia causes a leftward shift of the oxyhemoglobin dissociation curve, which results in a decrease in the P50 of hemoglobin. Although a leftward shift of the oxyhemoglobin dissociation curve is associated with decreased tissue availability of oxygen, this should be more than offset by the decreased oxygen consumption...
