What are synonyms for ventilation:perfusion ratio?

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 (V/O) o Considering that cardiac output is 5.0 L/min and alveolar ventilation is about 4.2 L/min, the overall ventilation: perfusion ratio is 0-8. Idealy, therefore, each alveolus should have a V/Q ratio of 0.8. However, that is not so even in normal lungs.

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. Ventilations-Perfusions-Verhältnis = V / Q Diagnosis of pulmonary embolism (PE) by visual interpretation of ventilation/perfusion (V/Q) scans is limited by the high percentages of patients classified in the intermediate- and low-probability categories.

1611 Objectives: To evaluate the feasibility of lobar ventilation/volume ratio (V/Vol ratio) and perfusion/volume ratio (P/Vol ratio) as parameters of lobar function, we did pulmonary ventilation/perfusion (V/Q) scan using SPECT/CT in our institute. Methods. Technetium-99m gas and technetium-99m macroaggregated albumin (MAA) were used in pulmonary V/Q scan under SPECT/CT. Data of ventilation

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 Q̇ or Q – perfusion – the blood that reaches the alveoli via the 2020-11-25 · A ventilation-perfusion ratio (V/Q) of infinity occurs when the alveolus is ventilated but not perfused. Since there is an absence of blood flow to the unit, the alveolar gas tension is the same as inspired air. Ventilation can be related to perfusion using the ventilation-perfusion ratio (V̇/Q̇). If alveolar ventilation is 4 L/min and pulmonary blood flow is 5 L/min, then the V̇/Q̇ ratio equals 0.8.
