Presented at High Frequency Ventilation Conference, Snowbird Utah, April 4-9, 2000
Deadspace Changes Produce Definable Chest Wall Alterations in Acoustic Output During High Frequency Ventilation. Goldstein M, Sorkin P, Correnti J, et al. Glendale CA.
Previous studies by this group have demonstrated that acoustic output measured with a microphone on a test lung can be used to can be used to estimate various pulmonary functions data and adequacy of lung expansion while on HFOV. This study demonstrated that increasing extrapulmonary dead space was also associated with reproducible acoustic changes.
Comment. Possible clinical usefulness of this technology awaits further refinement and clinical testing.
