Respiratory Flashcards
What is cystic fibrosis?
defective chloride transporter; meconium ileum, steatorrhea, bronchiectasis
What is obstructive lung disease?
mucus filled lungs can’t get air OUT; ratio decreased (< 80%)
What is the Light Criteria?
Effusion protein/ serum protein > 0.5
Effusion LDH/ serum LDH > 0.6
Effusion LDH > 2/3 upper limit of normal serum LDH
one or more = exudate
What is asthma?
chronic inflammatory disease of the airways
characterized by variable and recurring symptoms;
wheezing on expiration;
elevated IgE and eosinophils
What is restrictive lung disease?
