Bicarbonate ions are crucial for regulating blood pH. A person's breathing rate influences the level of CO2 in their blood. Breathing that is too slow or shallow causes respiratory acidosis, while breathing that is too rapid leads to hyperventilation, which can cause respiratory alkalosis.
Barb and Sandra just finished running a marathon. The women used different breathing techniques while running: Barb took very slow, shallow breaths while Sandra took very rapid breaths. Neither woman was feeling very well after the race and went to the medical tent to get checked out.
Is Sandra more or less likely than Barb to have respiratory alkalosis?
