Central venous pressure and plasma Na concentration during drinking behavior in the dehydrated dog.
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.
