The effect of various intermittent positive pressure breathing devices on cardiac output has been studied by Motley’ in a group of normal patients. He found that decreases in cardiac output were directly related to the height of the mean mask pressure. It was part of his conclusion that intermittent positive pressure breathing could be used without decreasing cardiac output when the pressures w...

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 advanta...

postoperative low cardiac output states are a major cause of postoperative mortality in infants and children following corrective cardiac surgery or congenital heart defects. whole body hypothermia has been used since 2001 in the management of these low output states when they are refractory to conventional modes of therapy. from december 2001 to april 2006, 25 cases were included in this study...

The variability of Doppler echocardiographic estimation of cardiac output at the aortic orifice was investigated in eight healthy subjects. Cross sectional echocardiograms of the aortic orifice and aortic Doppler velocities were recorded and measured by four echocardiographers. Between subject variability was significantly larger than within subject variability for all variables. Variability ow...
