Do relaxation exercises such as yoga, deep breathing, massage or meditation.Eat a healthy diet and get regular exercise.We can apply these assumptions to the ideal gas law ( PV = nRT) to derive an equation for the physiological dead space:īoron, W. The volume of the alveoli (V A) that participated in gas exchange, together with the physiological dead space (V D), will equal the volume of the expired air: V A+V D=V E.The molar amount of CO 2 produced in the alveoli ( n A CO 2) will be the same amount that is expired ( n E CO 2).The subject breathes in normal room air, and respiration (production of CO 2) happens everywhere, except in the volume occupied by the dead spaces. ![]() Physiological dead space is the sum of the anatomical dead space and the alveolar dead space. In the ideal healthy adult, this is zero. However, it is quick enough that it can be approximated (averaged out) as an abrupt transition.Īlveolar dead space includes those parts of the respiratory zone that do not participate in gas exchange. Note that in practice, O 2 is replaced by N 2 more gradually, as a sigmoid curve.
