restrictive 1 Flashcards
main feature of restrictive
reduced expansion leading to decreased TLC and decreased FVC
acute lung injury
abrupt onset of significant hypoxemia and diffuse pulmonary infiltrates in the absence of cardiac failure
2 types of acute lung injury
acute respiratory distress
respiratory distress syndrome of the newborn
acute respiratory distress
mostly seen in adults
respiratory distress of the newborn
low birth weigh, prematurity
acute lung injury mortality
40%
acute lung injury histologically
diffuse alveolar damage with hyaline membranes, hemorrhagic and heavy lungs, reactive proliferation of type 2 pneumocytes
chronic interstitial lung diseases
heterogenous group of disorders
inflammation and fibrosis of the pulmonary connective tissue, mainly interstitial between. the alveolar walls
common features of chronic interstitial lung diseases
reduced compliance - stiffening
reduced diffusion capacity
reduced lung volume
4 categories of interstitial lung diseases
- fibrosing
- granulomatous
- smoking related
- eosinophil
fibrosing diseases
usually interstitial pneumonia non specific interstitial pneumonia cryptogenic organising pneumonia autoimmune related pneumoconiosis
granulomatous
sarcoid
hypersensitivity pneumonitis/extrinsic allergic alveolitis
idiopathic pulmonary fibrosis
unknown cause
temporally heretrogenous process
fibroplastic foci - focal areas of nodules of fibrous tissue
honey comb lung
fibroplastic foci
focal areas of nodules of fibrous tissue
idiopathic pulmonary fibrosis survival
<5 years
