What is a common consequence of prolonged hyperventilation?

Prolonged hyperventilation leads to a decrease in carbon dioxide (CO2) levels in the blood, a condition known as respiratory alkalosis. When a person hyperventilates, they exhale CO2 at an increased rate, causing a reduction in the concentration of CO2 in the bloodstream. CO2 is a critical component in maintaining the acid-base balance in the body; lower levels of CO2 result in a higher pH, indicating alkalosis.

As the blood becomes more alkaline due to the decreased CO2, a series of physiological responses may occur, including symptoms like lightheadedness, tingling in the extremities, and possibly even fainting. The body tries to restore balance through compensatory mechanisms, but prolonged hyperventilation can significantly upset normal physiological conditions, affirming the connection between it and respiratory alkalosis.
