Recent advances in theoretical models of respiratory mechanics
Acta Mechanica Sinica/Lixue Xuebao, 2012 As an important branch of biomedical engineering, respiratory mechanics helps to understand the physiology of the respiratory system and provides fundamental data for developing such clinical technologies as ventilators.

Respiratory mechanics in mechanically ventilated patients with respiratory failure
Journal of Applied Physiology, 1985In 11 mechanically ventilated patients, respiratory mechanics were measured 1) during constant flow inflation and 2) following end-inflation airway occlusion, as proposed in model analysis (J. Appl. Physiol. 58: 1840–1848, 1985. During the latter part of inflation, the relationship between driving pressure and lung volume change was linear, allowing ...

Ventilation and Respiratory Mechanics
Comprehensive Physiology, 2012Abstract During dynamic exercise, the healthy pulmonary system faces several major challenges, including decreases in mixed venous oxygen content and increases in mixed venous carbon dioxide. As such, the ventilatory demand is increased, while the rising cardiac output means that blood will have considerably less ...

Mechanics of the Respiratory Muscles
Comprehensive Physiology, 2011Abstract This article examines the mechanics of the muscles that drive expansion or contraction of the chest wall during breathing. The diaphragm is the main inspiratory muscle. When its muscle fibers are activated in isolation, they shorten, the dome of the diaphragm descends, pleural pressure (

Mechanics of respiratory muscles
Respiratory Physiology & Neurobiology, 2008Lung ventilation is a mechanical process in which the respiratory muscles are acting in concert to remove air in and out of the lungs. Any alteration in the performance of the respiratory muscle may reduce the effectiveness of ventilation. Thus, early diagnosis of their weakness is vital for treatment and rehabilitation. Different techniques, which are

How to breathe? Respiratory mechanics and breathing pattern.
Respiratory Physiology & Neurobiology, 2019On theoretical grounds any given level of pulmonary or alveolar ventilation can be obtained at various absolute lung volumes and through many combinations of tidal volume, breathing frequency and inspiratory and expiratory timing.
