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...

Association of physical examination with pulmonary artery catheter parameters in acute lung injury.

29 Sep 2009 OBJECTIVE: To correlate physical examination findings, central venous pressure, fluid output, and central venous oxygen saturation with pulmonary artery catheter parameters. DESIGN: Retrospective study. SETTING: Data from the multicenter Fluid and ... Read more...

Management of a stenotic right ventricle-pulmonary artery shunt early after the Norwood procedure.

30 Aug 2009 BACKGROUND: Inadequate pulmonary blood flow through a right ventricle-to-pulmonary artery (RV-PA) shunt early after the Norwood operation can be remedied by adding a modified Blalock-Taussig (mBT) shunt. We used multiscale computational modeling to ... Read more...

Definition: The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).

Descriptor UI: D002302

Alternative terms: Cardiac Output; Cardiac Outputs; Output, Cardiac; Outputs, Cardiac;

Allowable Qualifiers: drug effects; genetics; immunology; physiology; radiation effects; ethics;

Tree Number: E01.370.370.380.150; G09.330.380.124;

History Note: 67(64)

Technical Notes: a physiol concept: do not confuse with the C14 diseases CARDIAC OUTPUT, HIGH or CARDIAC OUTPUT, LOW
