Effect of Mouthpiece, Nose Clips, and Head Position on Airway Area Measured by Acoustic Reflections

Journal of Applied Physiology, 1987

Authors: I. Rubinstein, P.A. McClean, R. Boucher, N. Zamel, J.J. Fredberg, and V. Hoffstein

Conclusion: “Acoustic reflection technique is so far the only relatively simple, noninvasive, reproducible, and inexpensive technique that permits the measurements of upper airway anatomy under dynamic conditions.”

Effect of Position and Lung Volume on Upper Airway Geometry

Journal of Applied Physiology, 1987 Authors: J. M. Fouke and K. P. Strohl Conclusion: “The occurrence of upper airway obstruction during sleep and with anesthesia suggests the possibility that upper airway size might be compromised by the gravitational effects of the supine position. We used an acoustic reflection technique to image airway geometry and made…

Reproducibility and Accuracy of Airway Area by Acoustic Reflection

Journal of Applied Physiology, 1984 Authors: L. J. Brooks, R. G. Casitle, G. M. Glass, N. T. Griscom, M. E. B. Wohl, and J. J. Fredberg Conclusion: “We conclude that the measurement of Airway Area by Acoustic Reflection yields accurate and highly reproducible results that may be clinically useful for the noninvasive detection of changes…
