Anotācija Electrical Impedance Tomography (EIT) is a technology capable of supplementing spirometry in a number of applications due to the ability to evaluate regional changes in lung volume. EIT measurements require 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 undershirt could increase the area of EIT applications such as daily respiratory monitoring in hospitals, at home, during physical activity, etc. The goal of the present paper was to demonstrate the usability of textile electrodes for EIT measurements. The conductive textile was integrated in the chest of a long sleeves thermal undershirt to form three rows of 16 circumferential electrodes that can be connected to a commercially available EIT monitoring system. Two healthy male volunteers aged 45–50 performed tidal breathing, deep breathing, and FRC maneuvers. The breathing volumes and FRC were measured using a body plethysmograph. The course of measurements demonstrated that contact between skin and textile electrodes are not tight enough to operate with the EIT device. Applying additional pressure to the electrodes and the use of electrolyte spray reduced the impedance of the textile electrodes to adequate values. Under such conditions, there were no differences in correlation coefficients between spirometry volumes and EIT volumes obtained using either conventional or textile electrodes.
