What is the effect of hyperventilation on blood levels of CO2?

Hyperventilation occurs when an individual breathes at an increased rate and depth, leading to excessive exhalation of carbon dioxide (CO2). This process results in a reduction of CO2 levels in the blood, a condition known as hypocapnia.

As the breathing rate increases, more CO2 is expelled from the lungs than is being produced by the body’s metabolic processes. Consequently, this reduction in CO2 levels can disrupt the acid-base balance in the body, often leading to respiratory alkalosis. Understanding this physiological response emphasizes the importance of maintaining appropriate ventilation to regulate CO2 levels and sustain homeostasis within the body.
