How does hyperventilation affect blood pH? Hyperventilation. Hyperventilation is when you are breathing far more quickly and deeply than normal. It is typically caused by stress, fear, anxiety, etc. If it is not calmed quickly, hyperventilation can have serious consequences, such as changed blood pH levels. Answer and Explanation: Hyperventilation causes the pH level of the blood to rise. pH measures acidity levels and low pH indicates high acidity. So when pH levels in the blood rise, the blood is actually becoming less acidic.
When the carbon dioxide level goes up in your blood, the pH goes down. In fact, your body looks for that change in pH and uses it to control the amount of oxygen which it sends to your muscles. When the pH of your blood goes down, your body is producing a lot of carbon dioxide.
