American Journal of Rhinology, 1994 Authors: V. W. S. Lai, J. P. Corey Conclusion: “Acoustic Rhinometry is a reliable technique for assessing the results of nasal provocation. This is a simple test to perform and is a good objective evaluation of the degree of nasal patency. Results are obtained quickly and consistently and are highly…
Clinical Otolaryngology, 1994 Authors: G. K. Scadding, Y. C. Darby, and C. E. Austin Conclusion: “Acoustic rhinometry has a definite advantage [to rhinomanometry] because it is not dependent on airflow in the nose, and it is therefore suitable for severely congested individuals. It also appears to be more sensitive to changes in obstruction, probably because…
American Journal of Rhinology, 1994American Journal of Rhinology, 1994 Authors: J. E. Buenting, R. M. Dalston, and A. F. Drake Conclusion: “The modified AR device (a narrow diameter wave tube) can be used to generate acceptably accurate area-distance functions of the infant nasal cavity.” “The modified AR device is best suited to analysis of nasal…
American Journal of Respiratory Critical Care Medicine, 1994 Authors: C. Van Surell, B. Louis, F. Lofaso, L. Beydion, L. Brochard, A. Harf, J. Fredberg, and D. Isabey Conclusion: “This study has demonstrated the feasibility of the acoustic reflection method in the intensive care unit and that the decrease in hydraulic diameter and the change in…
Journal of Applied Physiology, 1994 Authors: B. Louis, G. M. Glass, and J. J. Fredberg Conclusion: “In summary, we have shown that the two-microphone method permits accurate measurement of human pulmonary airway area of breathing subjects. We established a high-pass filter signal- processing method that lessened artifacts associated with nonrigidity. This is important because it…
