Theoretical Calculation of Resonant Frequencies of the Human Alveolar Wall and Its Implications in Ultrasound Induced Lung Hemorrhage

D. John Jabaraj and Mohamad Suhaimi Jaafar

Abstract—The human alveolar wall was modeled here as membranes and its resonant frequency was determined in order to analyze the mechanism of alveolar resonance of the ultrasound induced lung hemorrhage. The resonant frequency of the membrane models of the human alveolar wall was determined to be within the range of the frequency of diagnostic ultrasound used in the thoracic and abdominal regions; which is ≥ 2.5 MHz. Thus, the alveolar resonance is proved to occur during the diagnostic ultrasound imaging of humans. However the possibility of alveolar wall damage at resonance was not analyzed here. Nevertheless according to the resonant frequency equations derived here, the resonance of the alveolar wall by diagnostic ultrasound waves can be eliminated from occurring when total lung capacity is ~ 20% (at maximal expiration).

Index Terms—Alveolar resonance, lung hemorrhage, resonant frequency, ultrasound.
