WebStep-by-step explanation The ventilation-perfusion ratio - a ratio between the amount of air getting into the alveoli (alveolar ventilation in mL/min) and the amount of blood that is sent to the lungs (cardiac output in mL/min). V/Q = 0.8 = 8/10 = 4/5 Alveolar ventilation = 4mL/min : cardiac output = 5 Reference WebNeither alveolar ventilation nor capillary blood flow is uniform, the supply of air and blood never match perfectly even in healthy people Normal ventilation is 4L of air per minute, Normal perfusion is 5L of blood per minute This difference makes the expected VQ ratio 4:5 or 0.8 VQ Ratio higher than 0.8 = ventilation exceeds perfusion VQ Ratio … WebOct 24, 2024 · The V/Q ratio also changes considerably depending on where we are in the lung, from over 3 at the apex to below 1 at the base. We consider the V/Q ratio for a healthy lung as a whole to be just below 1, around 0.8, even though this is true only for the middle part of the lung, as seen on the figure. ultra hr fitbit bands
