WebDec 14, 2024 · Dead space represents the volume of ventilated air that does not participate in gas exchange. The causes of true dead space are (a) anatomical dead space and (b) alveolar dead space. Conditions that create a ‘dead space effect’ are (a) high V/Q units in a heterogenous lung, and (b) shunt. Physiological dead space = (PaCO2 – PECO2)/PaCO2.
