RS has smoked for many years and has developed chronic bronchitis, a chronic
obstructive pulmonary disease (COPD). He also has a history of coronary artery
disease and peripheral arterial vascular disease. His arterial blood gas (ABG)
values are pH, 7.32; PaCO2, 60 mm Hg; PaO2, 50 mm Hg; and HCO3-, 30 mEq/L.
His hematocrit is 52% with normal red blood cell indices. He is using an inhaled ß2
agonist and theophylline to manage his respiratory disease. At this clinic visit, it is
noted on a chest x-ray examination that RS has an area of consolidation in his
right lower lobe that is thought to be consistent with pneumonia.
Answer the following questions about RS’s situation.
1. What clinical findings are likely in RS as a consequence of his COPD? How
would these differ from those of emphysematous COPD?
2. Interpret RS’s laboratory results. How would his acid-base disorder be
classified? What is the most likely cause of his polycythemia?
3. What is the rationale for treating RS with theophylline and a ß2 agonist?
4. What effects would his respiratory disease have on his cardiovascular
function?
5. Considering both his COPD and pneumonia, in what position would RS have
the worst ventilation/perfusion (V/Q) matching?
