Answer:
decrease the work of breathing
Step-by-step explanation:
Restrictive airway diseases may be caused by interstitial diseases such as pulmonary fibrosis. These diseases are characterized by non-respiratory conditions that secondarily impede pulmonary expansion, such as muscle weakness, pleural diseases, obesity or kyphoscoliosis; and / or those that directly affect lung function, causing long-term hypercapnic respiratory failure.
Restrictive airway diseases refer to a group of thoracic deformities that result in inefficient coupling between the respiratory muscles and the rib cage. In general, disorders are characterized by a restrictive defect and share the potential for long-term hypercapnic respiratory failure.
