Conclusion: “Acoustic pulse reflectometry is a relatively recent technique which allows the non-invasive measurement of human airways. The technique consists of guiding an acoustic impulse through the subject’s mouth and into the airway. Suitable analysis of the
resulting reflection (the
European Respiratory Journal, 1991 Authors: V. Hoffstein, J. J.
