When you hyperventilate (breathe too fast), respiratory alkalosis (elevated blood ph) can occur, which can cause you to faint. a common but potentially dangerous method to reverse respiratory alkalosis is to hold a paper bag over your mouth and take normal breaths, thereby rebreathing the exhaled air. how might this method reverse respiratory alkalosis?

When you are hyperventilating, you are really taking in too much oxygen and the balance between O and CO2 is disrupted. By breathing in a paper bag, this can reverse respiratory alkalosis by allowing you to take back in your own carbon dioxide. Thus bringing down your elevated blood pH.
