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.
Blood pH: The acidity or alkalinity of blood. The pH of any fluid is the measure of the hydrogen ion (H-) concentration. A pH of 7 is neutral. The lower the pH, the more acidic the blood. A variety of factors affect blood pH including what is ingested, vomiting, diarrhea, lung function, endocrine function, kidney function, and urinary tract infection. The normal blood pH is tightly regulated between 7.35 and 7.45.
