Effect of the transpulmonary pressure on the lungs' vibroacoustic response: a first numerical perspective.

ABSTRACT: In the high-stakes environment of intensive care units (ICUs), managing transpulmonary pressure is crucial for providing breathing assistance to intubated patients, particularly when combining this intervention with respiratory therapy, such as high-frequency chest compression (HFCC). Despite the complexity of lung tissues, a computed tomography-based finite element model (CT-FEM), guided by Biot's theory, can be employed to numerically predict their vibroacoustic behavior at low frequencies, where the properties of the lungs align with the theory's principles. In this work, one aims to develop an analytical model of the lungs for two different levels of transpulmonary pressure-10 cm H₂O (inflated lungs) and 20 cm H₂O (healthy lungs)-to examine the poroviscoelastic be
