Summary The assumption that measurement of the transthoracic impedance can be used to assess variations of the airlblood volumes in the lungs has been tested. In cats transthoracic impedance, lung blood volume and lung air volume were recorded separately and the blood and air volumes varied independently. The results show that the trans‐thoracic impedance sensitively detects changes in the ratio between lung air and lung blood volumes. It is further indicated that impedance measurements can be used for evaluation of the magnitude of changes in this ratio.
