Question
Imagine that you have two people using breathing gear under water. Diver 1 is using an old style "rebreather" that removes carbon dioxide before the mixture is "rebreathed" and therefore decreases overall carbon dioxide concentrations in the blood. Diver 2 is using regular SCUBA gear and is breathing air with the normal amount of carbon dioxide that does not lower blood levels of carbon dioxide. Which diver would have a higher blood pH and which would feel more an "urge to breathe"?
a. Diver 2 would have higher blood pH and feel the "urge to breathe" sooner.
b. Diver 1 would have higher blood pH, while Diver 2 would feel the "urge to breathe" sooner.
c. Diver 2 would have higher blood pH, while Diver 1 would feel the "urge to breathe" sooner.
d. Diver 1 would have higher blood pH and would feel the "urge to breathe" sooner.
e. There would be no difference in blood pH or breathing between the two divers.
Answer is not d.
