WebVentilation/perfusion ratio. In respiratory physiology, the ventilation/perfusion ratio ( V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables: Q – perfusion – the blood that reaches the alveoli via the capillaries. The V/Q ratio can therefore be defined as the ratio of the amount of air reaching ... 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, … Web23.5.36 Define and explain the significance of forced vital capacity, forced expiratory volume (FEV), and maximum voluntary ventilation (MVV).
