What is the relationship between the blood pH and how fast you breath?

Answer 1

<>Actually, a very great deal! Your blood pH goes up and down mostly according to the amount of carbon dioxide in the blood. If you slow or stop your breathing, the carbon dioxide level goes up which decreases your blood pH (more acidic). More to the point, if your pH goes down because there is more CO2 in the blood, your respiratory rate will increase (unconsciously) in order to correct the condition. This is why people who are sick or have repiratory problems breathe fast.
People who hyperventilate will blow off too much CO2 and become alkalotic (high Ph).

Answer 2

Very little. The body would self regulate that. The oxygen in the air goes into solution with the blood, but does not really affect it. While there might be a small change, it isn't going to hurt you, and only lab equipment would see it.
