VQ MATCHING

[LyonN]

Hello just started class to become a paramedic does any one know what "V.Q. MATCHING" is?

V/Q stands for ventilation/perfusion. Why they have a "Q", makes absolutely no sense to me. Every healthy person has ventilation/perfusion matching. It's when you have a ventilation/perfusion "mis"match that you have a problem.

Either you're ventilating more than you are perfusing or you're perfusing more than you are ventilating. A PE would give you a V/Q mismatch, or pneumo, or Pickwickian Synrome (morbid obesity with hypoxic drive and known CO2 retention), yadda, yadda, yadda.

I tend to chase rabbits. I'm sorry if I did.

MSDeltaFlt gave a good summary of the concept. In addition to Ruffems suggestion, also try searching for "Ventilation Perfusion Mismatch". That will probably dig up a few more results then V/Q Matching or even V/Q Mismatch would.

If you have any more specific questions, feel free to post them and we'll do our best to answer them!

Makes sense thank you and trust me you'll be getting a lot of questions from me.

Here is a nice read that deals with a little more physiology by adding another dynamic to the discussion.
