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. This would result in a V/Q ratio of 1.0.

the ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung; because both ventilation and perfusion are expressed per unit volume of tissue and per unit of time, which cancel, the units become liters of gas per liter of blood.

I think it's a good idea. High Ventilation–Perfusion Ratio: Dead Space (C) When ventilation exceeds perfusion, dead space results (C). The alveoli do not have an adequate blood supply for gas exchange to occur.

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.

A normal Q value is around (perfusion) 5L of blood/minute. Therefore the Normal V/Q ratio is 4/5 or 0.8. When the V/Q is > 0.8, it means ventilation exceeds perfusion.
