The obligatory role of the kidney in long-term arterial blood pressure control: extending Guyton's model of the circulation.

30 Oct 2009 We describe a model for the essential role of the kidney in long-term blood pressure regulation. We begin with a simple hydraulic model for the circulation, with a constant circulating volume. We show, with the help of a modification of Guyton's ... Read more...

Metoprolol reduces cerebral tissue oxygen tension after acute hemodilution in rats.

30 Oct 2009 BACKGROUND: Perioperative beta-blockade and anemia are independent predictors of increased stroke and mortality by undefined mechanisms. This study investigated the effect of beta-blockade on cerebral tissue oxygen delivery in an experimental model ... Read more...

Pulmonary capillary blood flow and cardiac output measurement by partial carbon dioxide rebreathing in patients with acute respiratory distress syndrome receiving lung protective ventilation.

30 Oct 2009 BACKGROUND: Partial carbon dioxide rebreathing noninvasively measures the pulmonary capillary blood flow and estimates the cardiac output with the use of a predicted shunt value. It has been reported that the accuracy of the method is decreased in ... Read more...
