alveolar dead space
- physiologic dead space and anatomic dead space, representing the space in alveoli occupied by air that does not participate in oxygenâ€“carbon dioxide exchange (see alveolar ventilation, under ventilation). It varies in different parts of the lungs and under different conditions.
