WebJun 8, 2024 · Paradoxical Effect of Chest Wall Compression on Respiratory System Compliance. The lungs of patients with ARDS are characterized by marked heterogeneity, resulting in the coexistence of collapsed and hyperinflated tissue. Gravitational forces and chest wall geometry help govern the balance between these components. WebCompliance is a mechanical property used to describe the elastic behavior of the lung, chest wall, or respiratory system as a whole. ... If a lung has high elastance, it will by definition have a low compliance. It can also be helpful to think of compliance as the inverse of “stiffness.” A “stiff” tissue will have a low compliance. craftsman snowblower drive cable https://kibarlisaglik.com
