我们展示了使用电阻抗断层扫描光谱（EITS）来跟踪油酸引起的肺水变化的结果。在注射油酸之前和之后对三只山羊进行了测量。除了EITS测量外，还使用双指示剂技术测量肺水。肺电阻抗的大福尔斯下降是肺水增加的结果，但下降的大小是进行测量的频率的函数。这些变化已经使用科尔方程建模。还对两个提取的猪肺进行了四电极测量，并在将盐水引入肺中后进行了科尔方程建模。两组动物实验的结果相似。
We present the results of using electrical impedance tomographic spectroscopy (EITS) to follow the changes in lung water induced by oleic acid. Measurements were made on three goats before and after the injection of oleic acid. In addition to the EITS measurements, lung water was also measured using a double-indicator technique. Large falls in lung electrical impedance were seen as a result of the increase in lung water but the size of the fall was a function of the frequency at which the measurements were made. These changes have been modelled using the Cole equation. Four-electrode measurements were also made on two extracted porcine lungs and Cole equation modelling carried out following the introduction of saline into the lungs. Results were similar in the two sets of animal experiments.
