Effects of tap water, electrolyte solution, and spontaneous and furosemide-stimulated urinary excretion on thirst

Figure 2 Volume depletion by furosemide increased thirst only in volunteers who were thirsty before volume depletion was initiated (left); conversely, intravenous infusion of Ringer’s acetate solution (middle) and ingestion of tap water (right) decreased thirst only in those who were thirsty before the respective provocation (challenge) of the fluid balance.
