Water intake was reduced during the 1st day of hypobaric hypoxia (inspired O2 pressure of 75 Torr) to 35-40% of the normoxic level in both normal rats (N) and rats with diabetes insipidus (DI). Analysis of water intake under graded saline loads at several inspired O2 levels (inspired O2 fractional concentrations of 0.105, 0.120, and 0.2095) indicated that… CONTINUE READING
