Measurement of the Cardiac Output in Dogs by a Conductivity Method after Single Intravenous Injections of Autogenous Plasma

Equations are developed for the estimation of cardiac output from hematocrit dilution, using the continuously recorded conductivity of whole blood drawn from an artery through a conductivity cell, after a single intravenous injection of autogenous plasma. The equipment used is described, the results...

Description
Summary:Equations are developed for the estimation of cardiac output from hematocrit dilution, using the continuously recorded conductivity of whole blood drawn from an artery through a conductivity cell, after a single intravenous injection of autogenous plasma. The equipment used is described, the results are compared with those of simultaneously performed measurements of dye dilution and the advantages of the method are discussed.
