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 "rebreather" 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.
