The wife of an elderly patient with chronic obstructive pulmonary disease (COPD) calls the physician because her husband is extremely short of breath and appears "blue." The patient has a long history of COPD and has been compliant with his medications of albuterol inhalers, rotating antibiotics, and theophylline. His wife reports that, over the past several days, he has developed an increasingly productive cough. The patient is brought to the hospital by ambulance. At the hospital, the patient is barely responsive. He is breathing 100% oxygen via a tight-fitting face mask and no longer appears cyanotic. Which of the following is the most likely explanation for his unresponsiveness?
A. Aspiration
B. Hyperventilation
C. Hypoventilation
D. Myocardial ischemia
E. Pulmonary embolus

i think the explanation for COPD was like this:-
COPD----------> persistently low PO2------------> if given O2 (to 100%)-------> desensitise the chemoreceptor-------------> hypoventilation
