the ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung; because both ventilation and perfusion are expressed per unit volume of tissue and per unit of time, which cancel, the units become liters of gas per liter of blood.

Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs.

A VQ Mismatch in respiratory pathophysiology is a problem with either the Ventilation (air going in and out of the lungs) or the Perfusion (Oxygen and Co2 diffusion at the alvioli and the pulmonary arteries).
