Ventilation that does not meet metabolic needs (resulting in respiratory acidosis) is termed hypoventilation. Hypoventilation is indicated by the presence of an elevated PaCO₂. If alveolar ventilation increases, the lungs may remove carbon dioxide faster than it is being produced. In this case, PaCO₂ will fall below its normal value of 40 mm Hg, and pH will rise (i.e., respiratory alkalosis).
