Abstrakt: Objective. To examine the influence of the endotracheal tube (ETT) on respiratory reactance (X rs ) measured with the forced oscillation technique (FOT) and develop a correction method for it. Approach. In a bench study, the reactance of ETTs (X tube ) with different dimensions was measured on a breathing test lung in various respiratory settings. Main results. X tube can be accurately predicted by a fitted formula, with an R 2 of 0.97, with negligible effects due to changes in respiratory pattern and lung volume. Significance. The developed formula offers the ability to measure ETT-independent X rs values of patients, improving the potential of FOT for lung function testing in mechanically ventilated newborns.
