76 Mean arterial PO 2 declines with age 77 as does the pulmonary transfer factor for carbon monoxide (TLCO). 75 These changes in gas exchange could result from a variety of factors, including increased heterogeneity of ventilation-perfusion ratio Perfusion was measured using arterial spin labeling. Ventilation (ml·min(-1)·ml(-1)) images were combined on a voxel-by-voxel basis with smoothed perfusion (ml·min(-1)·ml(-1)) images to obtain regional Va/Q ratio. Data were averaged for voxels within 1-cm gravitational planes, starting from the most gravitationally dependent lung. The V/Q Ratio. In respiratory physiology, the V/Q ratio refers to the ratio of ventilation to perfusion.

What is the Ventilation/Perfusion Ratio? The V/Q ratio refers to the amount of air that reaches the alveoli per minute compared to the amount of blood that reaches the alveoli per minute. Ideally, the amount of oxygen and blood reaching the alveoli would be a perfect match.
