WebThe anatomic dead space is the gas volume contained within the conducting airways. The normal value is in the range of 130 to 180 mL and depends on the size and posture of the subject. The value increases slightly with large inspirations because the radial traction exerted on the bronchi by the surrounding lung parenchyma increases their size. WebDec 8, 2024 · This is a fairly narrow topic, and can be summarised easily: Consequences of increasing dead space. The effect on gas exchange is the same as the effect of decreasing the tidal volume. Decreased CO 2 clearance. Decreased oxygenation due to increased alveolar CO 2. Decreased efficiency of ventilation. For any given minute volume, CO 2 …
