30%

17
Q

What are the ideas behind the hygiene hypothesis?

18
Q

How do you diagnose asthma? (3)

A
  • Recurrent episodes of airway hyperresponsiveness and obstruction

19
Q

True or false: coughing may be the only symptom of asthma

A

Expiratory

Not always present

21
Q

What are the two major meds that exacerbate asthma?

A

NSAIDs

Beta blockers

22
Q

Why does ASA cause asthma exacerbation?

A

Shunts arachidonic acid to leukotrienes, which increases bronchoconstriction

23
Q

What happens to the expiratory phase with asthma?

A

Prolonged

24
Q

What is pulsus paradoxus?

A

an abnormally large decrease (10 mmHg) in systolic blood pressure and pulse wave amplitude during inspiration

25
Q

What causes the palpable liver and spleen with asthma?

Hyperinflation of the lungs

26

What is the obstructive pattern of spirometry (values)?

A

FEV1 less than 0.8

FEV1/FVC less than 65%

Not at all.

Elevated IgE
Eosinophilia

28

A
  • hyperinflation
  • Peribronchial thickening
  • atelectasis
  • pneumothorax
29
Q

What are the defining characteristics of a psychogenic cough?

A
  • Will completely disappear at night

- Increased with attention to cough

30
Q

What age group is most commonly affected with vocal cord dysfunction?

A
