What is restrictive lung dz?
|
Can't get air in, Caused by a decrease in the amt of air that lungs can hold, "stiff lungs reduce ability to expand w/inhalation. FEV1/FVC increased or normal
|
|
Causes of Restrictive lung dz?
|
Pleural, Alveolar, Interstitial, Neurmuscular, Thoracic cage.
|
|
Causes of Restrictive lung dz Pleural;
|
Dzs of the pleura that restrict lung expansion & decrease lung volume (pleural effusions or pleural thickening)
|
|
Causes of Restrictive lung dz Alveolar;
|
Dzs of aveolar spaces that prevent air from filling those spaces (pneumonia, CA & pulmonary edema)
|
|
Causes of Restrictive lung dz Interstitial;
|
Dzs contracting the space in the lung parenchyma between the alveoli (interstitium) reducing lung volumes (sarcoidosis, pulmonary fibrosis, silicosis & pneumoconiosis)
|
|
Causes of Restrictive lung dz Neuromuscular;
|
Normal lung parenchymia w/a inability to take a deep breath (diaphragmatic paralysis, Guillain-Barre syndrome, myasthenia gravis & amyotrophic lateral sclerosis)
|
|
Causes of Restrictive lung dz Throacic cage;
|
Skeletal abnormalities w/normal lungs (kyphoscoliosis, obesity)
|
|
What is Obstructive lung dz?
|
Air can't get out, Decrease in the amt of air expired from the lungs, Caused by narrowing or blockage of the airways. FEV1/FVC decreased
|
|
(Causes of Obstructive Lung Disease) Mechanical obstruction of the airways;
|
Foreign body, Tumor, Chronic mucus plugging in Chronic bronchitis.
|
|
(Causes of Obstructive Lung Disease) Increased resistance in the airways;
|
Airway thickening from inflammation in chronic bronchitis.
|
|
(Causes of Obstructive Lung Disease) Increased tendency for airway closure;
