Obstructive dz (dilated)

COPD, Bronchiectasis

2

Obstructive (constricted)

Asthma

3

Intrathoracic Restrictive (constricted)

Fibrosis, Sarcoidosis, pneumoconiosis

4

Extrathoracic Restrictive

Chest Cage, kyphosis, spondyloitis, obesity, neurousc (M.gravis, GB syndorme, muscular dystrophy

5

Normal FEV1/FVC

>80%

6

Obstructive dz FEV1/FVC

<80%

7

Restrictive dz FEV1/FVC

>80%

8

COPD

dec FEV1, dec FEV1/FVC, inc TLC, dec DLCO, inc RV

9

Asthma

dec FEV1, dec FEV1/FVC, inc TLC, nl/inc DLCO, inc RV

10

Restrictive intrathoracic

dec FEV1, nl FEV1/FVC, dec TLC, dec DLCO, dec RV

11

Restrictive extrathoracic

dec FEV 1, nl FEV1/FVC, dec TLC, N DLCO, inc RV

12

best test restrictive vs obstructive

TLC

13

asthma

restrictive low FEV1, normal FEV1/FVC, low TLC

14

DLCO 140% predicted, normal FEV1/FVC and TLC

alveolar hemorrhage

15

Inc DLCO

CHF, MS, ASD/VSD, PDA, pvera

16

Dec DLCO

COPD, restrictive lung dz, PE, pHTN, anemia

17

Normal DLCO

asthma, CO poisoning

18

Fixed extrathoracic

tumors/trachela stenosis both inspir (bottom) and exp(top) loops blunted

19

Dynamic extrathoracic obstruction

epiglottitis, Vocal cord dysfxn (insp - bottom loop blunted)

20

Dynamic intrathoracic obstruction

intrathoracic tracheomalacia - exhal (upper) loop blunted

21

Asthma

reactive to dust, viral, cold, exc, - must show reversible bronchospasm

22

Asthma dx

PFT - obstructive changes with reversible broncospasm - responds to brochodilators (inc FEV1 by 15%) - if no obst - methacholinie challenge test (15%)

23

Young man h/o asthma acute asthmatic attack treated with albuterol nebs - f/u now PFT will show

Obstructive defect (still has asthma dx)

24

35yo M paroxysmal non-prod cough >6months - no ohther sx - spirometry normal, no improvement with anti-histamine/cough meds

methacholine challenge test r/o asthma

25

woman in car factory SOB at work, worse at end of day, better at home, cxr normal

check peak flow at home AND home

26

Best way to tx patient with asthma

remove offending agent (PPI do not inc or dec sx of asthma)

27

Pt with asthma/eczema moves to new apt, asthma worse - with rug

remove rug, get plastic wraps for mattress, pillow etc

28

Asthma therapy Intermittent 80

no daily meds, rescue short acting beta

29

therapy mild persistent (>2/wk, 2/month, FEV1 >80%

low dose inh steroid, cromolyn, leukotriene, theophylline

30

Mod persistent - daily sx, >5/month at night, FEV1 60-80

low - med dose inh steroid + long acting beta (no beta without inh steroid)
