What do the word parts 'ventilation' and 'perfusion' actually mean?
+
'Ventilation' comes from the Latin word meaning 'to fan' or 'to air out'—it describes air moving in and out of the lungs. 'Perfusion' comes from Latin meaning 'to pour through,' describing blood flowing to tissues. Together, they describe a balance between air and blood in the lungs.
What does 'ventilation-perfusion mismatch' mean in simple terms?
+
It's a situation where the lungs aren't properly matching up the air you breathe with the blood flowing through the lungs. Think of it like having water and a filter that aren't working together smoothly—the exchange doesn't happen as well as it should.
What is the short form or abbreviation for this term?
+
The abbreviation is 'V/Q mismatch' (sometimes written as 'VQ mismatch'). You say it by spelling out the letters: V-slash-Q mismatch, or simply 'V-Q mismatch.' The V stands for ventilation and the Q stands for perfusion.
What other medical words share the root 'ventilation'?

How would I use this term correctly in a sentence?
+
You might hear it said like this: 'The doctor explained that a ventilation-perfusion mismatch was affecting how much oxygen the patient's blood was carrying.' It describes a condition affecting how air and blood interact in the lungs.
