Pulmonary Diseases Flashcards
FEV1 (decrease)/FVC (unchanged): problem with getting the air out due to narrowing of the airways (tubular issue)
Emphysema, COPD, asthma, cystic fibrosis
Obstructive pulmonary disease
FEV1 (decrease)/FVC (decrease) = ratio unchanged: problem with getting the air in due to restriction on how much can be inhaled/expandability of the lungs (decreased compliance)
Pulmonary fibrosis, sarcoidosis, granulomas, ARDs
Restrictive pulmonary disease
Cough, wheezing, SOB
Measure FEV1/FVC ratio
Albuterol, corticosteroids, leukotriene modifiers, mast cell inhibitors
Asthma
Chronic wet cough, edema (cor pulmonale), SOB, O2 dependent, cyanosis, increased sputum, cardiovascular system affected
Chronic bronchitis (blue bloater)
Minimal/absent cough, use of accessory muscles, pursed-lip breathing, barrel chest, air-trapping, nail clubbing,
Emphysema (pink puffer)
Cellular debris/microbes deposited as “waste” in weak spots of the walls > can lead to infection
Bronchiectasis
Recurrent infections, wet cough (increased mucus), malabsorption (pancreatic insufficiency, malnutrition), diabetes
Clinical manifestations of Cystic Fibrosis
Chloride movement across the cell membranes affects sodium > improper movement of water
Thicker mucus - CF
Wheezing, dyspnea/tachypnea, low-grade fever
Inflammation in the lower airways
< 2 y.o. (smaller airways, size changes resistance)
RSV - respiratory syncytial virus
Broncholitis
Swollen/red throat, drooling, dysphagia, fever, stridor (high pitch)
Swelling of epiglottis
H. flu vaccine, H. flu, S. pnuemo
Epiglottitis
Inspiratory stridor, expiratory barking cough, low-grade fever
6 m.o. - 3 y.o.
RSV, influenza, M. Pneumo
Croup
Inflammatory response destroys Type 1 pneumocytes, hypertrophy/hyperplasia of Type 2 pneumocytes affects surfactant production
Lung tissue becomes scarred and tough
Idopathic pulmonary fibrosis
Non-caseating granulomas (no necrosis in WBC inflammatory response cells)
Common in the lymph nodes and lungs
Affect skin, eyes, spleen, liver, kidneys
Prevalent in African Americans
Sarcoidosis
Type III hypersensitivity (B-cell mediated)
Dusts enter respiratory system and cause immune response
Hypersensitivity Pneumonitis
Asymptomatic
Inorganic dust exposure (silicates, asbestos)
Pneumoconiosis
