WebbBohr equation. The Bohr equation, named after Danish physician Christian Bohr (1855–1911), describes the amount of physiological dead space in a person's lungs. This is given as a ratio of dead space to tidal volume. It differs from anatomical dead space as measured by Fowler's method as it includes alveolar dead space. Webb1 okt. 2005 · Shunt reduces the overall efficiency of gas exchange and results in arterial blood gas tensions closer to those of mixed venous blood, thus increasing the measured apparent physiological dead-space by increasing P a CO 2. 12 A method for correcting dead-space measurements for the effects of shunt has been reported by Kuwabara and …
