Bohr method physiologic dead space3/2/2024 ![]() MethodsĮxpired gases of seven lung-lavaged pigs were analyzed at different lung conditions using main-stream VC and multiple inert gas elimination technique (MIGET). The aim of this work was to validate VD Bohr using PACO 2 derived from volumetric capnography (VC) against VD Bohr with PACO 2 values obtained from the standard alveolar air formula. ( physiology ) The sum of the parallel and the serial dead spaces.Bohr’s dead space (VD Bohr) is commonly calculated using end-tidal CO 2 instead of the true alveolar partial pressure of CO 2 ( PACO 2).( physiology ) The sum of the anatomic plus the alveolar dead spaces.Because this is a functional measurement, the volume is called the physiologic dead space. Lippincott Williams & Wilkins Ninth edition.īohr's method measures the volume of the lung which does not eliminate CO 2. West, Respiratory Physiology: The Essentials. ( physiology ) That volume of air in the lung that does not eliminate carbon dioxide, as defined functionally by the Bohr equation.( physiology ) That volume of air in the lung which does not partake in gas exchange.Throughout this paper, the term physiological dead space will be used to refer to the volume of the conducting airway down to the location at which a large change in gas composition occurs. This definition became inadequate once the alveolar dead space was described. ( obsolete ) The volume of the conducting airways of the lung. ![]() Physiologic dead space ( countable and uncountable, plural physiologic dead spaces) ![]()
