Restrictive or Interstitial Lung Disease Flashcards
Best indicator of a restrictive disorder
decreased lung compliance
restrictive lung disorders are characterized by
lungs that are difficulty to inflate
restricting volume
in restrictive is tidal volume and vital capacity increased or decreased?
decreased
restrictive lung disorder
a problem with the lung tissue itself rather than airways
though extraparenchymal damage impedes lung inflation
disease examples of restrictive lung disorder
pulmonary fibrosis
pulmonary edema
pneumonia
FEV1/FVC ratio in restrictive disorder
increased or normal ratio
FEV1/FVC ratio in obstructive disorder
decreased/reduced ratio
The values for residual volume and total lung capacity are generally (increased or decreased) in restrictive lung disease
decreased
condition characterized by excess connective tissue, particularly elastin in the lungs
pulmonary fibrosis
symptoms of pulmonary fibrosis
SOB cough fatigue weakness chest discomfort loss appetite rapid weight loss *progressive SOB on exertion (exercise)
classification of pulmonary fibrosis
a restrictive disorder that limits the ability of lungs to fill with air during ventilation process
causes of pulmonary fibrosis
exposure to environmental pollutants: abestos cigarette smoking autoimmunity infection idiopathic
mechanics of pulmonary fibrosis
exchange of prenchymal tissue with fibrotic
increase thickness of respiratory membrane
reduce gas exchange
decrease perfusion r/t compromised ability to provide oxygen to the blood
excess water in the lungs and accumulation of fluid in the extravascular spaces of the lungs
pulmonary edema
pulmonary edema is common complication of
cardiac disorders
CHF
ARDS
inhalation of toxic gases
