摘　　要：外源性气体再呼吸技术,采用持续的通气气体浓度分析方法是一种无创测定有效肺血流OEP的安全、简便、设计完善的方法。它明显地促进了CORB测定的临床使用。因此,我们用新的红外线声像光谱气体分析仪测定CORB和OEP并与COFICK（金标准）及心脏置管病人的COTD进行比较。Values of effective pulmonary blood flow (QEP) and cardiac output, determined by a non-invasive foreign gas rebreathing method (CORB) using a new infrared photoacoustic gas analyzing system, were compared with measurements of cardiac output obtained by the direct Fick (COFICK) and thermodilution (COTD) methods in patients with heart failure or pulmonary hypertension. The infrared photoacoustic gas analyser markedly facilitates clinical use of the rebreathing method in general, which makes the method available to a larger group of clinicians working with patients with cardiovascular diseases.
