This matching may be assessed in the lung as a whole, or in individual or in sub-groups of gas-exchanging units in the lung. On the other side Ventilation-perfusion mismatch is the term used when the ventilation and the perfusion of a gas exchanging unit are not matched. The actual values in the lung vary depending on the position within the lung.
A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.
The lung structure is important for the mechanism of ventilation-perfusion coupling. Pleura (plural: pleurae) is a single membrane surrounding the lung. It folds back to form two layers, and each layer is called parietal pleura and visceral pleura.

The template {{}} (a.k.a. {{glossary start}} or {{glossary begin}}) is used with {{glossary end}} to explicitly bracket a glossary or glossary-like description list (also called a definition list or association list), especially in a template-structured glossary, although such lists can be used more generally.
Microsoft Word allows creating both layout and content templates. A layout template is a style guide for the file styles. It usually contains a chapter which explains how to use the styles within the documents. A content template is a document which provides a table of contents. It might be modified to correspond to the user's needs.
Extended matching items/questions (EMI or EMQ) are a written examination format similar to multiple choice questions but with one key difference, that they test knowledge in a far more applied, in-depth, sense. It is often used in medical education and other healthcare subject areas to test diagnostic reasoning.
