What happens to the body during hyperventilation?

• A. Decreased oxygen levels
• B. Excess CO2 is removed
• C. Increased nitrogen levels
• D. Increased oxygen saturation

Answer: (B)

During hyperventilation, the rate of breathing increases significantly, leading to more carbon dioxide (CO2) being expelled than the body can produce. This excess removal of CO2 results in a state known as respiratory alkalosis, where the pH of the blood increases, making it more alkaline. The lowered levels of CO2 can lead to symptoms such as lightheadedness, tingling, and even fainting. The primary physiological change during hyperventilation is the rapid decrease of CO2 levels in the blood due to the increased respiratory rate, which is why this option is the correct choice. Other aspects, such as oxygen levels and nitrogen saturation, do not have the same direct correlation with hyperventilation as the removal of CO2.
