RESPIRATORY MECHANICS DURING FORWARD ACCELERATION*

Respiratory mechanics during forward acceleration.

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...

Volume acceleration as an index of respiratory drive during exercise.

In order to evaluate the applicability of volume acceleration (A(I)) at the onset of inspiration as an index of neuromuscular output, CO(2) rebreathing in six healthy subjects and incremental-load exercise in eight healthy subjects was performed while measuring A(I) and mouth occlusion pressure (P(0.1)). During CO(2) rebreathing, A(I) increased linearly with end-tidal CO(2) partial pressure and...

Respiratory mechanics and morphometric changes during pneumoperitoneum in normal rats.

Pneumoperitoneum may give rise to several respiratory changes; nevertheless, no comprehensive analysis of respiratory mechanics has been performed under this condition. Respiratory mechanics and thoracoabdominal morphometry were evaluated in six sedated, anaesthetized, paralysed, and mechanically-ventilated rats before (control) and during pneumoperitoneum. After airway occlusion at end-inspira...

Respiratory mechanics studied by forced oscillations during artificial ventilation.

Potential advantages of the forced oscillation technique over other methods for monitoring total respiratory mechanics during artificial ventilation are that it does not require patient relaxation, and that additional information may be derived from the frequency dependence of the real (Re) and imaginary (Im) parts of respiratory impedance. We wanted to assess feasibility and usefulness of the ...
