Anotācija Electro-impedance tomography (EIT) is a technology, capable to replace spirometry in a number of applications due to ability to evaluate changes in volumes of separate lung segments. EIT measurements required an array of conventional bio-potential electrodes, attached to the patient’s chest. Replacement of conventional electrodes with knitted conductive textile electrodes, integrated in a patient’s underwear, could increase the area of EIT applications, enabling daily respiratory monitoring in hospitals, at home, during physical activity etc. The goal of the present paper was to demonstrate usability of textile electrodes for EIT measurements. The conductive textile was integrated in the chest of the long sleeves thermal underwear t-shirt to form three rows of 16 circumferential electrodes each to be connected to the commercial EIT monitoring system Dräger® Infinity C500. Two healthy male volunteers aged 45 – 50 performed tidal breathing, deep breathing, and FRC maneuver. The breathing volume ad FRC was measured using spirometer, integrated into total body plethysmograph. The course of measurements demonstrated, that textile electrodes has too loose contact with the skin, due to this electrodes electric impedance exceeded the range, suitable for operation of the Infinity C500 EIT machine. Application of additional pressure to electrodes and use of electrolyte spray reduced impedance of textile electrodes to acceptable values. Under such conditions, there were no difference in correlation coefficient between spirometry volumes and ETI volumes, obtained using either conventional or textile electrodes.
