The article discusses research on the significant impact of organized secretions on the flow and resistance of endotracheal tubes (ETT). It references a study by Alison M. Wilson and colleagues, published in the October 2009 issue of "Chest" periodical. The researchers evaluated resistance through measuring the pressure drop at three flow rates using a mass flow meter and pressure transducer attached to a computer with specialized software. Wilson has recommended to clinicians the use of ETT as a potential source of resistance.
