EIT, electrical impedance tomography. ARDS, acute respiratory distress syndrome. COPD, chronic obstructive lung disease. TIns and TExp are the average values of absolute time differences for inspiration and expiration begin, respectively. /TV%, pendelluft amplitude to tidal variation ratio in percent. PEEP, positive end-expiratory pressure.
