WebJun 8, 2015 · In summary, increasing PaCO2 causes an increase in minute ventilation. The relationship between PaCO2 is fairly linear in the range of 45-80 mmHg; the rate of minute volume increases by 2-5L/min per every 1mm Hg of CO2 increase. The CO2/ventilation response curve is shifted to the left by metabolic acidosis and hypoxia. Sleep, sedation, … WebView the full answer.
