Medical Definition of Ventilation. Ventilation: The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs). Last Editorial Review: 5/13/2016.
Ventilation (V) is simply pertaining to inspiration and expiration of air (O2/CO2). Perfusion (Q) is the movement of blood (with the oxygen that has been inspired) to the tissues of the body. Remember, the exchange of gases only occurs at the capillaries on the alveoli of the lungs.E: Can someone explain ventilation-perfusion coupling to me?
