The Final Alveolar Dead Space Is Invariable, But

The final alveolar dead space is invariable, but The parity of volumes VD/VT is increased because of the reduced volumes of a breath and Exhalation. One of the most frequent reasons of deformation of a thorax - , at which. There is a reduction of vital capacity Lungs and reserve volume of an exhalation, while residual volume It is reduced moderately. Feature of this type of hypoventilation is that, What is the patients is usually long (to last stages of illness) Are compensated or , even in cases with serious Defects of a backbone. muscular infringements Patients with muscular infringements and Disorders usually have the reduced vital capacity of lungs and Decrease in volumes of the reserve exhalation, connected with secondary weakness Respiratory muscles and diaphragm. Residual volume of lungs, as Rule, it is not changed. Reduction of volumes of a lung and work interface Thorax muscles can lead secondary and To reduction of elasticity of a pulmonary fabric. Besides, VD/VT the relation Often happens increased because of the reduced volumes of a breath and an exhalation The syndrome and hypoventilation leads to increase.
