Respiratory Mechanics: To Balance the Mechanical Breaths!!

Fast breaths, slow breaths, small breaths, big breaths: importance of vagal innervation in the newborn lung.

IT IS WELL ESTABLISHED that vagally innervated mechanoreceptors in the lung influence respiratory frequency and the occurrence of spontaneous sighs (augmented breaths). Are these reflexes vitally important, or do they merely “fine tune” the respiratory pattern? The remarkable vitality and long-term survival of human patients and laboratory animals after denervation associated with lung transpla...

Structural Mechanics Approach to Investigate the Hyperelastic Mechanical Behavior of Single and Multi-wall Carbon Nanotubes

In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...

Respiratory Mechanics

Respiratory Mechanics by Theodore Wilson is a slim paperback volume (64 pages) describing three aspects of the way the lungs work: 1) pressure– volume relationships with regard to the lungs, 2) chest wall and muscles with regard to how the respiratory pump works, and 3) gas flow and transport. Relevant details about the author are missing, which I think is a loss. He is Emeritus Professor of Ae...

A new geometrical and mechanical relation in the respiratory system with airflow limitation—From the perspective of analytical respiratory mechanics

Classic respiratory mechanics is a branch of vectorial mechanics, which aims to recognize all forces acting on the respiratory system. Another branch of mechanics, analytical mechanics, has been used for analyzing the motions of complicated systems with constraints through equilibrium among scalar quantities such as kinetic energy and potential energy. However, until now, there have not been an...
