This study was designed to assess the accuracy and problems of noninvasively measuring right
and left cardiac output at various sampling sites by range gated pursed Doppler echocardiography.
High correlations were found between Fick-and Doppler-derived measurements of systemic and
pulmonary flow as well as the pulmonary to systemic flow ratio in 21 patients undergoing cardiac
catheterization (systemic flow [n=21] r=0.81; plulmonary flow [n=29], r=0.78;Qp/Qs... |
