目标。提出了一种提高临床呼吸多气体分析仪响应时间的算法。方法：研究方法。该算法涉及将二阶微分方程式应用于实时分析气体输出信号。将调整后的分析器输出信号与四极呼吸质谱仪同时采样和分析的信号进行了比较。结果。我们的结果表明，调整后的临床气体分析仪与质谱仪信号之间存在密切的相关性。在模型试验肺中，使用调整后的临床气体分析仪和质谱仪信号，非侵入性正弦惰性气体强制技术得出的肺体积显示了类似的结果。结论。该算法改善了临床气体分析仪的相对较慢的响应时间，适用于逐个呼吸的时间依赖应用。同样的算法也可以应用于响应时间较慢的其他仪器。
Objective. An algorithm to improve the response time of a clinical respiratory multigas analyser is presented. Methods. The algorithm involves the application of a second order differential equation to the analyser gas output signals in real-time. The adjusted analyser output signals are compared with those of a quadrupole respiratory mass spectrometer sampling and analysing simultaneously. Results. Our results show a close correlation between the adjusted clinical gas analyser and the mass spectrometer signals. Lung volumes derived from a non-invasive sinusoidal inert gas forcing technique, in a model test lung, using the adjusted clinical gas analyser and the mass spectrometer signals demonstrated comparable results. Conclusions. The algorithm provides an improvement on the relatively slow response times of the clinical gas analyser for breath-by-breath time-dependent applications. The same algorithm can also be applied to other instruments which have slow response times.
