Andrew B. Lumb, Deborah Horner, in Pharmacology and Physiology for Anesthesia, 2013 Ventilation in Relation to Perfusion. Ventilation can be related to perfusion using the ventilation/perfusion ratio ().If alveolar ventilation is 4 L/min −1 and pulmonary blood flow 5 L/min −1, then the ratio equals 0.8. If ventilation and perfusion of all alveoli were the same, then would be 0.8 throughout

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.

For each gas exchanging unit, the alveolar and effluent blood partial pressures of oxygen and carbon dioxide ( P O2 and P CO2) are determined by the ratio of alveolar ventilation to blood flow ( V ′A /Q Key Concepts:• Ventilation and Perfusion must be matched at the alveolar capillary level.• V/Q ratios close to 1.0 result in alveolar PO2 close to 100 mmHg and PCO2 close to 40 mmHg.• V/Q greater than 1.0 increase PO2 and Decrease PCO2. V/Q less than 1.0 decrease PO2 and Increase PCO2.• Definition of ventilation-perfusion ratio in the Definitions.net dictionary. Meaning of ventilation-perfusion ratio. What does ventilation-perfusion ratio mean? Ventilation Perfusion Ratio.

Synonym: Ventilations-Perfusions-Quotient Englisch: V/Q ratio. 1 Definition. Das Ventilations-Perfusions-Verhältnis gibt das Verhältnis zwischen der Lungenbelüftung V (pulmonale Ventilation) und der Lungenperfusion Q (entspricht dem Herzzeitvolumen) an. 2 Berechnung.

Explanation 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.
