Q

Chronic inflammation causes structural changes and a narrowing of the small airways and destruction of the lung parenchyma that leads to the loss of alveolar attachments to the small airways and decreases lung elastic recoil.
Cigarette smoke and an occupation that involves regular exposure to a dusty environment are the two major external factors.

Overnight PSG - to exclude underlying causes… if nothing shows up then
Perform MSLT- multiple sleep latency test -

51
Q

how to tx narcolepsy?

A

Stimulat meds- dextroamphetamine and methylphenidate
Modafinil = wakefulness promoting agents (not amphetamine based = less risk of habit forming, longer acting = increased insomnia risk)
Cataplexy tx with REM suppressing meds = SSRIs, SNRIs, y-hydroxybutyrate

Method for reading CXR

A

AABCDF Method

  • Adequacy
  • Airways
  • Bones
  • Circulation
  • Diaphragm
  • Final Look
62
Q

step 1: Adequacy

A

Pt identifiers, who read it, marker from tech (L, R), costophrenic angles visible, apices (top) of lungs visible, dark area above clavicle, full inspiration (defined as 9 or more ribs above diaphragm)

63
Q

Step 2 airways

A

Is the trachea midline (sometimes slightly shifted with enlarged thyroid), bronchi, look side to side and top to bottom and compare
Left lung: 2 lobes; upper, lower (middle area called the lingula, butts up against border of the heart)

64
Q

Step 3 Bones

A

Sternum, ribs, scapula; as well as spinal process and clavicles

65
Q

Step 4: Circulation (heart and vessels)

A

Measure cardiac ratio (can ONLY do in PA film)
Take widest heart dimension compared to widest lung dimension; should be half the size or less of lung
Mediastinal borders
Aortic knob
LV (make sure you can see it + size)
RA

66
Q

Step 5 Diaphragm

A

Shape (domed, shaped like 2 hills), height (R 1-3cm higher → normal because liver is below), costophrenic angles

67
Q

Step 6 Final Look

A

Corners of the film, tracheal deviation, retrocardiac lung (lateral view), “below” the diaphragm if visible, peri-hilar regions

68
Q

more comprehensive than spirometry! (done in pulmonary office)
Looks at lung vol, gas exchange, diffusion capacities and more

A

PFT

69
Q

Simplest PFT test, looks at vol of inspiration and expiration at 1 and 6 seconds; done in the office
Must withhold inhalers night before for test to be effective

A

Spirometry

70
Q

obstructive lung diseases

A

reduction in airflow- some air remains in lung after full expiration
COPD
ASTHMA
CHF

71
Q

restrictive lung diseases

A

reduction in lung volume - difficulty taking air inside the lung
- interstitial lung disease, scoliosis, neuromuscular cause

72
Q

If FVC/FEV1 both low, but ratio normal

A

restrictive lung diseases

73
Q

low FEV1: FVC ratio

A

obstructive lung diseases

74
Q

A

FEV1: VC ratio

75
Q

method If testing for obstructive lung pattern with spirometry

A

Albuterol 2-4 puffs, wait 15 min → repeat test
If measures >12% or 200mL → reversible obstructive pattern (asthma)

If no reversal
If don’t fit pattern for COPD; refer to pulmonology for PFTs, bronchoprovocation testing
