متن کاملCardiac output response to norepinephrine in postoperative cardiac surgery patients: interpretation with venous return and cardiac function curves.
OBJECTIVE We studied the variable effects of norepinephrine infusion on cardiac output in postoperative cardiac surgical patients in whom norepinephrine increased mean arterial pressure. We hypothesized that the directional change in cardiac output would be determined by baseline cardiac function, as quantified by stroke volume variation, and the subsequent changes in mean systemic filling pres...
متن کاملA computational model-based validation of Guyton's analysis of cardiac output and venous return curves.
Guyton developed a popular approach for understanding the factors responsible for cardiac output (CO) regulation in which 1) the heart-lung unit and systemic circulation are independently characterized via CO and venous return (VR) curves, and 2) average CO and right atrial pressure (RAP) of the intact circulation are predicted by graphically intersecting the curves. However, this approach is v...
متن کاملThe role of the vasculature in regulating venous return and cardiac output: historical and graphical approach.
PURPOSE To review the physiology of cardiac output regulation by the peripheral vasculature. This will enable the clinician to understand and manage the complex circulatory changes in various forms of shock, and in other common altered circulatory states encountered in anaesthetic practice. SOURCE Articles were obtained from a Medline review (1966 to present; search terms: shock, venous retur...
متن کاملErratum to: Volume and its relationship to cardiac output and venous return
Volume infusions are one of the commonest clinical interventions in critically ill patients yet the relationship of volume to cardiac output is not well understood. Blood volume has a stressed and unstressed component but only the stressed component determines flow. It is usually about 30 % of total volume. Stressed volume is relatively constant under steady state conditions. It creates an elas...
