Medical treatment for restrictive lung disease is normally limited to supportive care since both the intrinsic and extrinsic causes can have irreversible effects on lung compliance. [10] The supportive therapies focus on maximizing pulmonary function and preserving activity tolerance through oxygen therapy, bronchodilators, inhaled beta ...
Bronchiolitis obliterans results in worsening shortness of breath, wheezing, and a dry cough.The symptoms can start gradually, or severe symptoms can occur suddenly. [9] [10] These symptoms represent an obstructive pattern that is non-reversible with bronchodilator therapy, and need to be related to various lung insults. [11]
Respiratory diseases, or lung diseases, [1] are pathological conditions affecting the organs and tissues that make gas exchange difficult in air-breathing animals. They include conditions of the respiratory tract including the trachea , bronchi , bronchioles , alveoli , pleurae , pleural cavity , the nerves and muscles of respiration .
Pulmonary function testing in people with organizing pneumonia, either cryptogenic or due to secondary causes, shows a restrictive defect with a decrease in the gas absorptive capacity of the lungs (seen as a decrease in the diffusion capacity of carbon monoxide). [9] Airflow obstruction is usually not seen on pulmonary function testing. [9]
Such scar tissue causes an irreversible decrease in oxygen diffusion capacity, and the resulting stiffness or decreased compliance makes pulmonary fibrosis a restrictive lung disease. [14] Pulmonary fibrosis is perpetuated by aberrant wound healing, rather than chronic inflammation. [15] It is the main cause of restrictive lung disease that is ...
Extrapulmonary restriction is a type of restrictive lung disease, indicated by decreased alveolar ventilation with accompanying hypercapnia.It is characterized as an inhibition to the drive to breathe, or an ineffective restoration of the drive to breathe.
