Effects of hyperventilation on CO2 and pH levels. Alidrin Armandico. Physiology Lab 142. Egle Ortega. Aprill 25, 2014. Abstract. The aim of this experiment was to analyze how pH and carbon dioxide (CO2) levels in the blood change during hyperventilation and how the renal system compensates for this condition. Hyperventilation decreases CO2, increases pH, and lowers H+ levels which then results to respiratory alkalosis.
