Your patient with chronic ventilatory failure and hypoxemia has been given supplemental oxygen. Within an hour, he is found to be breathing shallowly and very lethargic. The physician suspects that he was given too much oxygen. What physiologic effects could have led to this?
1) Oxygen-induced redistribution of the ratio
2) Oxygen-induced peripheral chemoreceptor depression
3) Respiratory acidosis
4) Increased shunt percentage
