The Ventilation-Perfusion Ratio (V'/Q' Ratio) of a normal lung is not uniform and displays variation along its vertical axis when an individual is standing upright. The vertical variation in the (V'/Q' Ratio) is simply a product of the relative vertical variations in pulmonary blood flow and ventilation distribution.

Ventilation/perfusion ratio From Wikipedia, the free encyclopedia In respiratory physiology, the ventilation/perfusion ratio (V̇/Q̇ ratio or V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables: V̇ or V – ventilation – the air that reaches the alveoli
