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