PaCO 2 vs. alveolar ventilation (VA). The relationship is shown for carbon dioxide production rates of 200 ml/min and 300 ml/min. A decrease in alveolar ventilation (VA) in the hypercapnic patient will result in a greater rise in PaCO 2 than will the same VA change when PaCO 2 is low or normal. Also, an increase in carbon dioxide ...

As the respiratory rate increases or becomes deeper, additional CO2 is removed causing decreased acid (H+) levels in the blood and increased pH (so the blood becomes more alkaline).
