Indicator-dilution measurement of cardiac output with dissolved hydrogen.
Dissolved HL has been used as an indicator for measuring cardiac output by the techniques of constant-rate injection and sudden, single injection indicator dilution. Because of its low solubility, H2 is eliminated essentially quantitatively in the lungs and recirculates negligibly. The constant-rate injection technique involves the gas chromatographic measurement of pulmonary (or systemic) arte...
متن کاملOverestimation of left ventricular volume by the indicator dilution technique.
• Since the work of Bing and co-workers and the subsequent observations of Holt, the indicator dilution technique has been used to measure ventricular volume. The validity of the technique depends upon thorough mixing of indicator with ventricular blood. However, experimental data have been presented by Irisawa et al. and subsequently by Swan and Beck suggesting that requisite mixing does not o...
متن کاملReproducibility of double indicator dilution measurements of intrathoracic blood volume compartments, extravascular lung water, and liver function.
STUDY OBJECTIVE Arterial thermal dye dilution (TDDart) with the COLD system (Munich, Germany) allows measurement of cardiac index (CI), partial blood volumes, lung water, and liver function. The aim of the study was to determine agreement of TDDart measurements with pulmonary artery thermal dilution measurements (TDpa) and to assess the reproducibility of TDDart parameters. DESIGN Prospective...
متن کاملIndicator-dilution studies with "diffusible" indicators.
• The indicator-dilution principle has been applied to studies of the circulation in order to provide estimates of flows and volumes in the vascular compartment. A sine qua non of validity of these estimates is that the indicator used remain within the confines of: the vascular compartment for the entire duration of the period required to obtain appropriate samples of blood. In such a symposium...
متن کاملMeasurement of mitral regurgitation by indicator-dilution techniques.
CONSIDERABLE progress has been made in recent years in the quantitative estimation of certain cardiovalvular abnormalities by cardiac catheterization.' The quantitative determination of mitral regurgitation has not yet reached a similar status despite a substantial amount of experimental effort. This article will give theoretical bases for determination of mitral regurgitation by indicator-dilu...
