“…See text for discussion. respired volume (Kubicek et al 1964, Ashutosh et al 1974, but rather with the current through the lung tissue using a fairly narrow geometrical configuration corresponding to the electrodes through which the current was applied (Kira et al 1971). Hence, inductance belts and TI do not measure the same physical quantity and the expected correlation must be somewhat limited.…”

“…These quantities can be easily measured non-invasively in real time by transmitting a known low-amplitude and low-frequency current (I) and measuring voltage drop (ΔV) across electrodes attached to the thorax. Numerous studies have shown that change in trans-thoracic impedance as a function of time can be correlated with breathing [ 17 , 18 ].…”

“…Electrical impedance of biological tissue has been a subject of research for more than 40 y [1,2] with applications ranging from respiratory plethysmography [3] to cardiac stroke volume measurement [4] to detection of bladder cancer [5]. Original bioimpedance analyzers were cumbersome, requiring careful matching of resistors and a large overall number of components.…”
