M2 Pulmonary Formatives - Key Facts

Question 1

Emphysema - Pathophysiology Keys (2)

Answer 1

1) Increased Dead Space (High V/Q Ratio)

2) At first matching is okay

Question 2

Decrased Diffusion Capacity - Causes (2)

Answer 2

1) Emphysema - Decreased Surface Area

2) Restrictive/Fibrotic Disease

Question 3

V/Q Ratio - Emphysema vs. COPD

Answer 3

Emphysema = High = High Dead Space
COPD = Low = Hypoventilation = Shunt

Question 4

Chronic Cough Causes (3)

Answer 4

1) GERD
2) Astham
3) Post-Nasal Drip

Question 5

Deacreased vs. Increased V/Q Ratio

Answer 5

Decreased = Low Ventilation = High CO2
Increased = High Ventilation = Low CO2
