28
Q

MG/ALS, phrenic nerve paralysis, scoliosis :

Obstructive or Restrictive?

A

Restrictive

29
Q

Obstructive FEV1/FVC?

A

< 80% Predicted

30
Q

Restrictive FEV1/FVC?

A

Normal

31
Q

Obstructive TLC and RV?

A

↑ >120% predicted

32
Q

Restrictive TLC and RV?

A

↓ <80% predicted

33
Q

Obstructive / Restrictive?

Improves >12% with bronchodilator

A

Obstructive: Asthma does, COPD and Emphysema don’t

Restrictive: Nope

34
Q

Obstructive / Restrictive?

DLCO reduced?

A

Obstructive: Reduced in Emphysema 2/2 alveolar destruction.

Restrictive: Reduced in ILD due to fibrosis thickening distance

35
Q

Criteria for diagnosis of COPD?

A

Productive cough >3mo for >2 consecutive yrs

36
Q

Treatment of COPD?

A

1st line = Ipratropium, Tiotropium.

2nd Beta agonists.

3rd Theophylline (Narrow therapeutic window, Arrhythmias)

37
Q

COPD Indications to start O2?

A

PaO2 <55 or SpO2<88%. If cor pulmonale, <59

38
Q

COPD: Criteria for exacerbation?

A

Change in sputum, increasing dyspnea

39
Q

Treatment for COPD Exacerbation?

A

ABX (Macrolide) and Steroids

O2 to 90%

Albuterol / Ipratropium nebs

PO or IV corticosteroids

FQ or macrolide ABX

40
Q

Best prognostic indicator for COPD?

A

FEV1 (Spirometry)

41
Q

Shown to improve mortality in COPD?

A
  1. ) Quitting smoking (can decr rate of FEV1 decline
  2. ) Continuous O2 therapy >18hrs/day
42
Q

Why is our goal of SpO2 94 - 95% instead of 100% in COPD?

A

COPDers are chronic CO2 retainers.

Hypoxia is the only drive for respiration.

43
Q

Important vaccinations for COPDers?

A

Pneumococcus Vaccine w/ a 5yr booster

and

Yearly influenza vaccine

44
Q

New Clubbing in a COPDer?

A

Hypertrophic Osteoarthropathy (Cancer)

Acute Onset of Clubbing –> Lung Cancer

Next best step… get a CXR

Most likely cause is underlying lung malignancy

45
Q

Asthma:

If pt has sxs twice a week and PFTs are normal?

A

Mild Intermitant

Albuterol only

46
Q

Asthma:

If pt has sxs 4x a week, night cough 2x a month and

PFTs are normal?

A

Moderate-Intermittant

Albuterol and Inhaled CS

47
Q

Asthma:

If pt has sxs daily, night cough 2x a week and FEV1 is

60-80% predicted value?

A

Moderate-Consistant

Albuterol + inhaled CS + Long-acting beta-ag (salmeterol)

48
Q

Asthma:

If pt has sxs daily, night cough 4x a week and FEV1 is

<60%?

A

Severe

Albuterol + inhaled CS + Salmeterol + Montelukast and
Oral steroids

49
Q

Asthma Exacerbation?

A

Tx w/ inhaled albuterol and PO/IV steroids.

Watch peak flow rates and blood gas.

PCO2 should be low.

Normalizing PCO2 means impending respiratory failure
–> INTUBATE!
