Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, [2] resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity.
When used without qualification, it usually refers to an environmental disease of the lung, also known more specifically as pulmonary siderosis or Welder's disease, which is a form of pneumoconiosis. Pulmonary siderosis was first described in 1936 from X-ray images of the lungs of arc welders .
Caplan syndrome is a nodular condition of the lung occurring in dust-exposed persons with either a history of rheumatoid arthritis (RA) or who subsequently develop RA within the following 5–10 years. [3] The nodules in the lung typically occur bilaterally and peripherally, on a background of simple coal workers' pneumoconiosis. There are ...
The disease puts strain on the heart, which may lead to heart failure and leg swelling. Obesity hypoventilation syndrome is defined as the combination of obesity and an increased blood carbon dioxide level during the day that is not attributable to another cause of excessively slow or shallow breathing .
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 .
Exposure to coal dust is the cause of coalworker's pneumoconiosis, also called "black lung disease", is an interstitial lung disease caused by long-term exposure (over 10 years) to coal dust. Symptoms include shortness of breath and lowered pulmonary function. It can be fatal when advanced.
Signs and symptoms of white lung pneumonia can vary based on what caused the illness in the first place, Dr. Ganjian says. However, these are the most common pneumonia symptoms, according to the ...
While a lung biopsy is the gold standard, some clinicians opt against this due to the risks of the procedure. Lung biopsies performed on patients with NSIP reveal two different disease patterns – cellular and fibrosing – which are associated with different prognoses. The cellular pattern displays chronic inflammation with minimal fibrosis.
