Biography

Departments of Cardiac Sciences, University of Calgary, Alberta, Canada, In this pilot study of the renal circulation we applied the reservoirwave approach, a time-domain method for the analysis of arterial pressure and flow that defines the magnitudes of the series resistances that account for the total vascular resistance of an organ.

 Application of the Reservoir Wave Approach to the Renal Circulation

In this pilot study of the renal circulation we applied the reservoirwave approach, a time-domain method for the analysis of arterial pressure and flow that defines the magnitudes of the series resistances that account for the total vascular resistance of an organ. Renal and systemic pressures and flows were measured in anesthetized dogs. Unilateral infusions of angiotensin II (ANG II) or endothelin-1 (ET-1) decreased renal conductance by 30% and 50%, respectively. These decreases in conductance were acc... view more»
