Abstract

Changes in circulating blood volume, plasma Na concentration, and central venous pressure (CVP) after fluid intake were monitored continuously in water-deprived dogs. When dogs were allowed free access to fluid (tap water or 0.9% saline), rapid satiation appeared before any systemic changes in blood composition took place, and CVP increased remarkably (about 6 mmHg) in association with drinking behavior. The possible roles of CVP as a controlling factor of drinking were hypothesized.
