Influence of neonatal endotracheal tube dimensions on oscillometry-acquired reactance: a bench study

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 r...

Description
Summary: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. X can be accurately predicted by a fitted formula, with an R of 0.97, with negligible effects due to changes in respiratory pattern and lung volume. The developed formula offers the ability to measure ETT-independent X values of patients, improving the potential of FOT for lung function testing in mechanically ventilated newborns.
