Dead space (physiology) - Wikipedia
WEBDead space is the volume of air that is inhaled that does not take part in the gas exchange, because it either remains in the conducting airways or reaches alveoli that are not perfused or poorly perfused. It means that not all the air in each breath is available for the exchange of oxygen and carbon dioxide.

WEBJul 12, 2019 · Dead space is the fraction of tidal volume which does not participate in gas exchange. It is composed of apparatus dead space and physiological dead space. Physiological dead space is usually measured by the Enghoff modification of Bohr's method, and consists of anatomical and alveolar dead space.
