Name the Causes of ARDS (10)
ARDS
A= Aspiration vs. [Acute Pancreatitis] vs. [Air Fluid Embolus (amniotic)]
R= Radiation
D= Drugs vs. DIC vs. Drowning
S= Sepsis vs. Smoking vs. Shock
ARDS is a restrictive pattern that –> ⬇︎Lung Compliance, Pulm HTN and impaired gas exchange
Tx for ARDS
PEEP (Positive End Expiratory Pressure)
Based on GOLD Criteria, how should COPD pts be treated?


What is the 4 Criteria for COPD Exacerbation
- SOB
- ⬆︎Cough
- Sputum ∆
- BL wheezing w/ respiratory acidosis
Tx for COPD Exacerbation-4
Which improves survival? Which ⬇︎future events?
“I’m having COPD Exacerbation! Give me DOPA! (but not really)”
- Duoneb (albuterol + ipratropium)
- O2 PRN via BiPAP (goal: 90-94% O2 Sat) -only when desat
- [Prednisone 40 mg qd x 5]
- Abx (Azithro-⬇︎future events or Levoflox or Doxy)
Criteria for Pulmonary HTN ; What are causes?-7
Pulm Arterial presure ≥25 (normal = 20);

- L Heart Dz = MOST COMMON
- Drugs (see image)
- [Limited CREST Scleroderma]
- SLE
- Recurrent VTE
- Idiopathic Primary
- Chronic Lung Dz
Difference between [Dead Space Ventilation] and [Physiological shunting]; Which causes Hypoxemia?
[Dead Space Ventilation] = Area of Lung that has Good Ventilation but poor perfusion
vs.
[Physiological Shunting] = Area of Lung with POOR Ventilation but good perfusion which—> physiological shunting –> Hypoxemia (Think PNA) - “You’ll get Shunts when the [VP is PG” = Ventilation Poor but Perfusion is Good]
What mediastinal masses are found in the…
A: Anterior mediastinum
B: Middle mediastinum
C: Posterior mediastinum
A: Anterior = Thymoma
B: Middle = Bronchogenic Cyst
C: Posterior = Neurogenic tumors (Meningocele/Lymphomas/Esophageal tumors)
For pts on ventilators, what are the best ventilator setting changes for ⬆︎ oxygenation-2 and why
- INC PEEP ( prevents alveolar collapse/Reopens old ones/Reduces shunting) AND Reduces mortality in ARDS pts
- INC FiO2 (note: >60% for long time–>proinflammatory O2 free radicals!)
Most common sx of Pulmonary Embolism-5

- Pleuritic Chest Pain
- SOB
- Cough
- Tachypnea
- Tachycardia

Physical Exam: Rales, low Fever, Hemoptysis
(LTOT-Long Term Oxygen Therapy) improves survival in Stage 4 COPD pts
When is LTOT indicated-3 and how long/day is it used?
- [PaO2 LOE 55 mm Hg] OR
- [Pulse Ox SaO2 LOE 88] OR
- FEV1 < 30%
should be used GOE 15 hours/day!
In Cor Pulmonale pts, PaO2 LOE 59 or SaO2 LOE 89
Describe the Approach to a PE pt

Classic Sx of Sarcoidosis-8
CCUBBEDD
Cardiac (Restrictive Cardiomyopathy)
HYPERCalcemia
Uveitis –> Vision loss
Bilateral Hilar LAD!
Bell’s Palsy
Erythema Nodosum (SubQ Fat lesions)
[Dry cough & Dyspnea]
Diffuse interstitial fibrosis
- elevated ACE and 1-25VitD production –> HYPERCalcemia and HYPERCalciuria*
- Image showing b/l Hilar LAD*

Sarcoidosis Etx-2 (Etiology)
[CD4 Helper T] inappropriately respond to environmental triggers + Suppressed TRegs –> Non-Caseating Granulomas in Lung

Image showing b/l Hilar LAD
Sarcoidosis Tx-4
“Sarcoidosis is a SCAM”
Steroids
Cyclosporine
Azathioprine
MTX
Image showing b/l Hilar LAD

How long does it take Malignant Pulm Nodules to double in size? How does this affect diagnostics?

1 month - 1 year; Pt with stable Pulm Nodule > 1 year = NO CA!

Bronchiectasis Etx

Recurrent Cycle of
[Poor mucociliary clearance –> Bacterial infection –> Inflammation –> Bronchial Dilation and thickening–> Cough w/tenacious sputum and Hemoptysis]
Dx = High Res CT Chest

Gold standard dx for Bronchiectasis

High Res CT chest scan (initial dx)

List the Obstructive causes of Bronchiectasis (2)
A:
1) Tumor
2) Foreign Body

List the Infectious causes of Bronchiectasis (2)
1) TB
2) [Aspergillus Fumigatus in ABPA]-Allergic BronchoPulmonary Aspergillosis] –> will be associated with [recurrent transient pulm infiltrates]

List the Congenital causes of Bronchiectasis (3)
1) Immunodeficient Syndromes
2) cystic fibrosis
3) Kartagener (1° Ciliary Dyskinesia)

List the Random causes of Bronchiectasis (3)
1) Rheumatoid Arthritis
2) Lupus
3) Graft

What is the most common cause of Hemoptysis
Bronchitis (usually [acute s/p viral infection] but could be chronic also)
Tx = supportive
Also think about: Bronchiectsis/TB/CA/Trauma/PE
Describe Bronchial Breath Sounds-2
[Loud short inspiration]
+
[Loud LONG EXPIRATION]
