blood. The normal range for ph is 7.35-7.45 and the normal range for PCO2 is 35-45 5. Describe what happened to the pH and the carbon dioxide in the blood with hyperventilation. With hyperventilation the ph increases and carbon dioxide decreases 6. Explain how returning to normal breathing after hyperventilation differed from hyperventilation without returning to normal breathing. When breathing is returning to normal‚ for about 10secs the breath is held in order to retain CO2 before returning
