![]() Perbandingan Berdampingan - Ruang Mati Anatomi vs Fisiologis dalam Bentuk Tabular 6. V d V t = P A C O 2 − P e C O 2 P A C O 2 Ī common step is to then presume that the partial pressure of carbon dioxide in the end-tidal exhaled air is in equilibrium with that gas' tension in the blood that leaves the alveolar capillaries of the lung. Kesamaan Antara Ruang Mati Anatomi dan Fisiologis 5. The original formulation by Bohr, required measurement of the alveolar partial pressure P A. The Bohr equation is used to quantify the ratio of physiological dead space to the total tidal volume, and gives an indication of the extent of wasted ventilation. Physiological dead space: This is the sum of anatomical and alveolar dead space. Alveolar dead space: This is the volume of air that reaches the alveoli but does not participate in gas exchange due to a lack of perfusion. ![]() It differs from anatomical dead space as measured by Fowler's method as it includes alveolar dead space. Anatomical dead space: This is the volume of air in the conducting airways that does not participate in gas exchange. This is given as a ratio of dead space to tidal volume. The Bohr equation, named after Danish physician Christian Bohr (1855–1911), describes the amount of physiological dead space in a person's lungs. Not to be confused with the Bohr model or the Bohr effect.
