During the following expiration, increases from 0% (pure dead space gas) to equilibrium (pure alveolar gas) (i.e.

Measurement Measurement of anatomical dead spaceīased on rapid dilution of gas already in lung (N2 or CO2) by inspired gas (100% O2). When using mask or anaesthetic circuit tubing, this adds to the conducting zone. during exercise), physiological dead space is reduced (due to reduction in alveolar dead space).Īlveolar dead space is the part of the inspired gas which passes through the anatomical dead space to mix with gas at the alveolar level, but does not participate in gas exchange.

The difference between anatomical dead space and physiological dead space is alveolar dead space. Physiological dead space is the part of the tidal volume which does not participate in gas exchange.

Write short notes on physiological dead space (1990)ĭefinition - the volume occupied by gas which does not participate in gas exchange in lung.Īnatomical dead space is the volume of the conducting airways.Īnatomical dead space is constant regardless of circulation.
